Journal of Combinatorial Theory

The Journal of Combinatorial Theory, Series A[1] and Series B,[2] are mathematical journals specializing in combinatorics and related areas. They are published by Elsevier. Series A is concerned primarily with structures, designs, and applications of combinatorics. Series B is concerned primarily with graph and matroid theory. The two series are two of the leading journals in the field and are widely known as "JCTA" and "JCTB".

The journal was founded in 1966 by Frank Harary and Gian-Carlo Rota.[3] Originally there was only one journal, which was split into two parts in 1971 as the field grew rapidly.
Influential articles

Influential articles that appeared in the journal include Katona's elegant proof of the Erdős–Ko–Rado theorem and a series of papers spanning over 500 pages, appearing from 1983 to 2004, by Neil Robertson and Paul D. Seymour on the topic of graph minors, which together constitute the proof of the graph minor theorem.
