Algebraic structures and their applications (ASTA) is an international mathematical journal founded in 2013. ASTA carries original research articles in the field of Algebra and combinatorics and publishes recent developments and new trends in algebra, with emphasis on the use of geometrical, topological, and combinatorial methods. The main subjects include (but are not limited to) hyperstuctures, ring and module theory, representation theory of algebras, homological algebra, category theory, homotopy theory, model theory and algebraic combinatorial theory. Also ASTA publishes paper which use algebraic structures in another fields, such as computer science and mathematical chemistry.
