Hagia Sophia Journal of Geometry (HSJG) (e-ISSN: 2687-4261) is a double-blind, peer-reviewed open access journal that publishes original research and review articles in geometry and in interdisciplinary areas of mathematics that employ geometric methods and investigate geometrical structures. In publication since 2019, HSJG adheres to the ethical standards of the Committee on Publication Ethics (COPE). Manuscripts must have a similarity rate below 25% (excluding references) and should be written in English. The journal does not charge any submission, processing, or publication fees. HSJG focuses on the following core areas: Algebraic number theory, Algebraic geometry, Linear and multilinear algebra; Matrix theory, Lie algebras and Lie superalgebras, Lie groups, Combinatorial geometry, Fractal geometry, Local analytic geometry, Noncommutative differential geometry, Geometry, Convex and discrete geometry, Differential geometry, Manifolds and cell complexes, Global analysis, Analysis on manifolds, Geometric probability and stochastic geometry, Numerical approximation and computational geometry, Geometry education, Hopf algebras, Quantum groups and related topics.

Beyond serving the professional academic community, HSJG is dedicated to fostering a culture of research at early educational stages. To encourage, appreciate, and reward intellectual activities beyond the classroom setting and to provide a platform for the development of research ideas, the journal explicitly welcomes original research articles from undergraduate students and high school students (developed in collaboration with their supervising teachers).
