Hagia Sophia Journal of Geometry (HSJG) publishes original research and survey papers in fields of geometry and all interdisciplinary areas in Mathematics which use geometric methods and investigate geometrical structures. HSJG covers the following main areas: differential geometry, manifolds, Lie groups, geometric algebra, finite geometries, combinatorial geometry, kinematic geometry, Euclidean geometry, non-Euclidean geometries, matrix theory, quantum groups , Hopf algebra and Clifford algebra.
