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.[citation needed]

)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.
An electronic, open access journal, Combinatorial Theory,[4] was announced in 2020. The new journal aims to be a continuation of JCTA independently from Elsevier. Most of the editorial board of JCTA resigned at the end of 2020, and part of them transitioned to Combinatorial Theory.[5][6][7] It published its first issue in December 2021.[8]
Influential articlesEdit
Influential articles that appeared in the journal include Katona's elegant proof[9] of the Erdős–Ko–Rado theorem and a series of papers spanning over 500 pages, appearing from 1983[10] to 2004,[11] by Neil Robertson and Paul D. Seymour on the topic of graph minors, which together constitute the proof of the graph minors theorem. Two articles proving Kneser's conjecture,[12][13] the first by László Lovász and the other by Imre Bárány, appeared back-to-back in the same issue of the journal.
