Hacettepe Journal of Mathematics and Statistics (HJMS) is an international, peer-reviewed journal dedicated to publishing high-quality, original research. The journal accepts only manuscripts written in English and does not charge any submission or publication fees. Submitted articles must align with the journal’s scope and meet the required quality standards; otherwise, they will not be considered for review. Manuscripts that have been previously published or are under consideration for publication elsewhere will not be accepted.

Submission Process

Manuscript submissions for the journal are processed through the DergiPark system. Submissions must be made via the corresponding author's account. To submit your manuscript, please register and log in to the submission portal at DergiPark Login. (https://dergipark.org.tr/en/login). 

• Copyright Release Form: Download the form from https://fs.hacettepe.edu.tr/stat/HJMS/HJMS-Copyright%20Transfer%20Form.pdf. Complete the necessary fields, sign the document, and upload the scanned copy to the DergiPark system.
• ORCID ID: Ensure that each author has an ORCID ID. If you do not have one, please register at ORCID from https://orcid.org/  

Plagiarism

The journal takes issues of copyright infringement, plagiarism, and other violations of best publishing practices very seriously. As part of the review process, manuscripts that lack proper form or exhibit a high similarity to existing sources, as detected by the iThenticate software (https://www.ithenticate.com/)  will be immediately rejected by the editor.  

• HJMS style_pdf (This is the compiled output of the TeX file in PDF format. It is not required but may be helpful.)
• HJMS style_tex
• HJMS_cls

It is essential to include all figure and table files, where applicable, along with the TeX file and class file during the submission process.

Option 2 (Employment of the Overleaf Template) For a collaborative and user-friendly environment, authors are encouraged to prepare their manuscripts using the official HJMS Overleaf template. The template includes all the necessary files and is accessible via the following link:  

• https://www.overleaf.com/latex/templates/hjms-latex-template/fqyyhgkjfzsx.

The online template provides all required files for manuscript preparation. Once the manuscript is completed, authors must download all files (including any figure and table files, where applicable) from Overleaf and upload them individually to the DergiPark system.

Note: The official Hacettepe University logo will be added later by the production editors of the journal. For both options, please ignore the following errors or warnings:

• "Package pdftex.def Error: File `h-eps-converted-to.pdf' not found: using draft setting."
• "File `h.eps' not found."

Preparation of Manuscripts

The following guidelines mut be adhered to when preparing manuscripts for submission to Hacettepe Journal of Mathematics and Statistics.

1. Title 

• The title of your manuscript should be clear, concise, and accurately reflect its content.
• A descriptive title that clearly conveys the topic of the manuscript will enhance its visibility in major indexing services. 

2. Abstract

• The manuscript should begin with a concise, descriptive title followed by an informative abstract of no more than 250 words.
• The abstract may include references but should avoid the use of abbreviations.
• If the abstract contains a citation, the authors' names, title, journal, and publication date should be enclosed in square brackets.

3. Keywords

• You are required to provide at least three keywords for indexing purposes. Keywords should be written in English.
• Only the first letter of the keywords should be capitalized, separated by commas, and there should be no dot at the end.
• Avoid using multi-word keywords that include terms like "and" or "of."
• Only use abbreviations in keywords if they are widely recognized and established in the field.

4. AMS Mathematics Subject Classification

• The manuscript must include the 2020 AMS Mathematics Subject Classification codes from https://mathscinet.ams.org/mathscinet/msc/msc2020.html  to categorize the content appropriately.
• Multiple classification codes should be separated by commas

5. Abbreviations

• Abbreviations should be defined at first mention and used consistently thereafter.
  

6. Figures and Tables

• Figures (minimum resolution: 300 dpi) and tables should be embedded within the text and numbered sequentially using Arabic numerals. 
• Each table and figure must have a descriptive caption explaining its components.
• Table captions should be placed above the table. 
• Figure captions should be placed below the figure.
• Figures, images, artwork, diagrams, and other graphical media must also be submitted as separate files along with the manuscript.
• All tables and figures must be cited in the manuscript text.
• The terms “Table x.” and “Figure x.” must be in bold, while the rest of the caption should be in regular font and end with a period. See examples: "Table 1. Comparison of two-point estimations for some values of the parameters." and  "Figure 3. Sampling distribution".
• Figures and Tables must be numbered consecutively and referenced in the text using proper LaTeX commands. Do not manually type figure or table numbers.
  

7. Equations

• Equations should be numbered sequentially in the order they appear in the text.
• Each equation must be centered on the page, with its corresponding number placed in parentheses and right-aligned. In the manuscript, equations should be referenced solely by their assigned numbers.
• Equations should be written in display math mode and must be numbered consecutively throughout the manuscript. Authors must use proper LaTeX  commands to refer to equations in the text rather than typing equation numbers manually.
  
• Equations must be written in editable text format, not as images. If a numbered equation is included, it should be properly cited within the text.

8. Citations

• When citing multiple references, arrange them in ascending numerical order (e.g., [2, 3, 16]).
• For consecutive references, use a range instead of listing each reference separately (e.g., [2-6] instead of [2, 3, 4, 5, 6]).
• Authors must ensure that all hyperlinks included in the manuscript are valid and functional at the time of submission.
• References must be cited in the text using proper LaTeX command (not typed manually). Every cited reference must appear in the bibliography, and every item in the bibliography must be cited in the text.

9. References 

• All references must be cited in the text, and any references cited within your article should also appear in your reference list.
• Corresponding citations must have identical spelling. References should be numbered and referred to in the text by the same number, enclosed in square brackets.
• References should be ordered alphabetically by the last name of the first author. If multiple works by the same author exist, they should be further ordered by the last name of the second author. If the authors are identical, the most recent work should be listed first.
• Journal names must be abbreviated according to ISO4 standards (https://www.issn.org/services/online-services/access-to-the-ltwa/), and volume numbers should be written in bold. There must be a space between the volume and issue numbers, but no comma should separate the journal name and issue number.
• Initials in author names should not have spaces between them (e.g., “M.M. Arat”). The word "and" should be included before the last author's name, without a comma preceding it.
• The first word of the article title should begin with an uppercase letter, and the remaining words should be lowercase. For books, all words in the title should start with uppercase letters. Please refrain from using quotation marks around publication titles. The title of the publication should be italicized.

10. Appendix Guidelines

• Appendices should appear after the “References” section.

11. Additional Sections in Manuscripts

• Acknowledgements: Provide details regarding any assistance received during the research or manuscript preparation process. 
• Author Contributions: Clearly specify the contributions of each author to the work presented in the manuscript. 
• Conflict of Interest: Declare any potential conflicts of interest related to the research or publication.
