Applied Categorical Structures《应用范畴结构》(双月刊). Applied Categorical Structures focuses on applications of results, techniques and ideas from category theory in particular to algebra, analysis, geometry, order, topology, physics and computer science. These include the study of topological and algebraic categories, representation theory, algebraic geometry, homological and homotopical algebra, derived and triangulated categories, categorification of (geometric) invariants, categorical investigations in mathematical physics, higher category theory and applications, categorical investigations in functional analysis, in continuous order theory and in theoretical computer science. In addition, the journal also follows the development of emerging fields in which the application of categorical methods proves to be relevant.
