Combinatorial Theory publishes original contributions that advance understanding of discrete structures exhibiting a high degree of combinatorial complexity.

The journal welcomes submissions that represent substantial advances in the fields of Additive, Algebraic, Analytic, Enumerative, Extremal, Geometric, Probabilistic and Topological Combinatorics, as well as theoretical aspects of their applications to other areas of mathematics and the sciences. The journal also welcomes high-quality submissions in these areas that organize, clarify, and simplify existing body of work.

In addition to  Research Article submissions, the journal also accepts Expository Article submissions, to encourage inclusion of valuable well-written expositions.
