TheJournal of Combinatorial Theory,Series A[1] andSeries B,[2] aremathematical journals specializing incombinatorics and related areas. They are published byElsevier.Series A is concerned primarily withstructures,designs, and applications of combinatorics.Series B is concerned primarily withgraph andmatroid theory. The two series are two of the leading journals in the field and are widely known asJCTA andJCTB.[citation needed]
The journal was founded in 1966 byFrank Harary andGian-Carlo Rota.[3] Originally there was only one journal, which was split into two parts in 1971 as the field grew rapidly.
In 2020, most of the editorial board ofJCTA resigned to form a new,open access journalCombinatorial Theory. The new journal aims to be a continuation ofJCTA independently from Elsevier.[4][5][6] It published its first issue in December 2021.[7]
Influential articles that appeared in the journal includeKatona's elegant proof[8] of theErdős–Ko–Rado theorem and a series of papers spanning over 500 pages, appearing from 1983[9] to 2004,[10] byNeil Robertson andPaul D. Seymour on the topic ofgraph minors, which together constitute the proof of thegraph minors theorem. Two articles provingKneser's conjecture,[11][12] the first byLászló Lovász and the other byImre Bárány, appeared back-to-back in the same issue of the journal.
