Applied Categorical Structures focuses on applications of results, techniques and ideas from category theory to mathematics, in particular algebra, analysis, order and topology and computer science. These include the study of topological and algebraic categories, representation theory, algebraic geometry, homological and homotopical algebra, derived and triangulated categories, categorical investigations in functional analysis, in continuous order theory, in algebraic and logical type theory, in automata theory, in data bases and in languages. In addition, the journal also follows the development of emerging fields in which the application of categorical methods proves to be relevant.

Applied Categorical Structures publishes both carefully refereed research papers and survey papers. It promotes communication and increases the dissemination of new results and ideas among mathematicians and computer scientists who use categorical methods in their research.
