A Direct Polynomial Solution of Nonlinear Volterra-Fredholm Integro-Differential Equations via the Shifted Chebyshev Collocation Method
Abstract
This study presents efficient direct numerical solutions for the nonlinear Volterra-Fredholm integro-differential equations (NVFIDEs). The main component of the numerical scheme is the collocation method, which uses shifted Chebyshev polynomials. The method converts the given NVFIDEs into a system of linear/nonlinear algebraic equations with unknown coefficients of the truncated shifted Chebyshev series. With the aid of Maple, unknown coefficients are obtained, and so, the desired approximation solution is achieved. Several numerical examples are presented to assess the accuracy by comparing them with other existing techniques in the literature and to evaluate the method's efficiency. From the tables and figures, the examples reveal that only a small number of shifted Chebyshev series terms are needed to achieve small errors.

Ethical Principles and Publication Policy
Mathematical Sciences and Applications E-Notes (MSAEN) has adopted the International Ethical Publication Principles on research and publication ethics published by the Committee on Publication Ethics (COPE), Directory of Open Access Journals (DOAJ), and Open Access Scholarly Publishers Association (OASPA).
MSAEN expects authors, editors, reviewers, readers, and publishing agencies to comply with ethical principles and publication policy sensitively.
1. Ethical Principles
1. Conflicts of Interest
Editors: Editors should not have personal or financial conflicts of interest with articles.
Reviewers: Referees should inform the journal editor about the evaluation process if they suspect any conflict of interest in the article they are evaluating, and refuse article evaluation if necessary. In order to prevent a conflict of interest, people in the institutions where the article authors are working cannot referee the article.
Authors: All authors should disclose in their manuscript any financial or other substantive conflict of interest that might be construed to influence the results or interpretation of their manuscript. All sources of financial support for the project should be disclosed.
2. Authorship of the Paper
Authorship should be limited to those who have made a significant contribution to the conception, design, execution, or interpretation of the reported study. All those who have made significant contributions should be listed as co-authors. Where there are others who have participated in certain substantive aspects of the research project, they should be acknowledged or listed as contributors. The corresponding author should ensure that all appropriate co-authors and no inappropriate co-authors are included in the paper and that all co-authors have seen and approved the final version of the paper and have agreed to its submission for publication.
3. Data
Journal Policies on Data Sharing and Reproducibility: The MSAEN strongly recommends author(s) submit supplementary material and data sets that illustrate the results shown in their papers. If any restrictions exist on the side of the author(s), these concerns should be shared with the editorial teams during the submission of scientific papers.
The MSAEN encourages author(s) to share data and make them publicly available if they do not violate human rights or other privacy issues. Authors are recommended to cite any data referenced in their studies. Cited data sets, apart from whether they are created by the author(s) or not, should be written in the reference lists of papers. Authors are also recommended to include a data availability statement.
Data Access and Retention: Authors are asked to provide the raw data in connection with a paper for editorial review and should be prepared to provide public access to such data, if practicable, and should, in any event, be prepared to retain such data for a reasonable time after publication.
Data fabrication: This is about generating research findings.
Data falsification: Manipulating research data to give a false impression. This includes manipulating images (eg, micrographs, gels, radiological images), removing outliers or "inappropriate" results, changing, adding, or skipping data points, etc., are included. Technically, the Image can be improved for the readability of the image. However, if there is such an improvement, the editor should be informed while the article is sent to the journal, and the article should also be included. Proper technical manipulation means adjusting the contrast and/or brightness or color balance if applied to the full digital image (not parts of the image). Improper technical manipulation means darkening, enhancing, deleting an image, and/or adding new elements.
4. Duplicate / Multiple Submission(s)
Manuscripts that are either found to have been submitted elsewhere or published elsewhere. If authors have used their own work, either previously submitted or published, as the basis for a submitted manuscript, they are required to cite the previous work. They also need to indicate how novel contributions are offered in their submitted manuscript, over and above those of the previous work.
5. Intellectual Property
- Authors certify that their submitted manuscript (and any supporting items) are their own intellectual property, and the copyright has not been transferred to others.
- Authors certify that the manuscript contains no plagiarism, no fabrication, no falsification, no manipulated citations, and that the manuscript conforms to JSS authorship policies.
- All manuscripts, revisions, drafts, and galleys remain the intellectual property of the author(s). Except as stated in the agreed license, the author(s) retain the copyright to their work.
- All review comments and reports remain the intellectual property of the reviewer or editor. Except as stated in the agreed license, the author(s) retain the copyright to their work.
- Authors, reviewers, and editors agree to keep all communications, comments, or reports from reviewers or editors confidential.
- Reviewers and editors agree to keep all manuscripts, revisions, and drafts confidential, with the exception of the final published galley(s).
6. Correction, Retraction, Expression of Concern
Editors may make corrections if they detect minor errors in the published article that do not affect the findings, interpretations, or results.
Editors may retract the article in case of major errors/violations that invalidate the findings and results.
Editors may issue a statement of concern if there is a possibility of abusive research or publication by the authors, if there is evidence that the findings are unreliable and the authors' institutions have not investigated the incident, or if the potential investigation seems unfair or inconclusive. COPE guidelines are taken into account with regard to the correction, retraction, and expression of concern.
7. Publication of Studies Based on Surveys and Interviews
Aiming to establish ethical assurance in scientific periodicals, the MSAEN journal adopts the principles of the "Code of Conduct and Best Practice Guidelines for Journal Editors" published by the Committee on Publication Ethics (COPE). In this scope, the following aspects should adhere to the studies submitted to the journal:
Ethics committee approval should be obtained for research conducted in all the disciplines that require ethics committee approval, and this approval should be stated and documented in the article.
In studies that require ethics committee approval, information about the approval (committee name, date, and issue number) may be included in the method section of the study. However, in the case of reports, information about the informed consent and the signed consent form should be included in the Article Information Form at the end of the article.
The studies that require ethics committee approval are as follows:
• Any research conducted with qualitative or quantitative approaches that requires collecting data from participants.
• Studies conducted on humans,
• Retrospective studies in accordance with the law on the protection of personal data,
Also;
• A statement confirming that an "informed consent form" has been received in case reports,
• Obtaining permission from the owners for the use of scales, surveys or photographs belonging to others,
• A statement confirming that copyright regulations are met for the intellectual and artistic works used.
8. Policy of Publishing Additional or Special Issues
A special issue can be published in our journal once a year upon the request of the Editorial Board. The publication processes of the articles sent to be included in the special issue are the same as the standard processes.
- Additional or Special issue: An issue published in addition to the regular issues of a periodically published journal. It may consist of conference papers or a series of articles focusing on a specific topic.
- Page numbering in the additional or special issue is different from the regular issues.
- The print run of the additional or special issue cannot be more than one-third of the regular issue. The special issues containing conference paper abstracts are not included in this scope.
- Ratios of case reports, compilations, and research articles (excluding conference paper abstracts) published in the additional or special issue will be included in the ratios of articles published in other issues.
- The issues published as a tribute are not accepted as additional or special issues. Their page numbering and organization are the same as the regular issues.
Plagiarism: Showing others' original ideas, methods, data, or works as their own work, partially or completely, without reference to scientific rules.
Forgery: Using data that does not actually exist or has been falsified in scientific research.
Distortion: Falsifying the research records or data obtained, displaying the equipment or materials not used in the research as if used, distorting or shaping the results of the research in the interests of the people and organizations that provide support.
Republishing: Presenting repetitive publications as separate publications in academic appointments and promotions.
Slicing: Dividing the results of research into pieces in an improper way or in a way that disrupts the integrity of the research, and publishing each one separately to increase the total publication count for academic appointments and promotions.
Unfair Authorship: Including non-contributors in the author list or not including those who have contributed, changing the author's order in an unjustified and inappropriate manner, removing the names of contributors from the work in subsequent editions, using influence to include names among the authors despite not being contributors.
Other ethical violations include:
a) Not specifying the supporting individuals, institutions, or organizations and their contributions in the publications made as a result of research conducted with support.
b) Using theses or studies that have not yet been submitted or have not been accepted as a source without the permission of the owner,
c) Not complying with ethical rules in research on humans not respecting patients' rights in publications,
d) Violating the provisions of the relevant legislation in biomedical research and other clinical research related to humans,
e) Sharing the information in a work that has been assigned for review with others before it is published without the explicit consent of the author,
f) Misusing resources, spaces, facilities, and equipment provided or allocated for scientific research,
g) Deliberately making a false and ungrounded allegation about the ethical violation,
h) Publishing the data obtained from surveys conducted as part of a scientific study without the explicit consent of the participants or without the permission of the relevant institution if the study is conducted in an institution,
ı) Failing to obtain written permissions from authorities that are required for starting research activities or experiments,
k) Conducting research activities or experiments in violation of the related legislation or the provisions on research and experiments in the international conventions to which Turkey is a party,
l) Disregarding the obligation to inform and warn the relevant authorities about possible harmful practices related to scientific research.
m) Not using the data and information obtained from other individuals or institutions in scientific studies to the extent and as permitted, not respecting the confidentiality of this information and not ensuring its protection,
n) Making false or misleading statements regarding scientific research and publications in academic appointments and promotions.
