On factorization of monoids in Cartesian categories Mesablishvili, Tamar Cartesian category Monoid Descent cohomology The problem of factorization of groups and monoids in a Cartesian monoidal category C is investigated. Two necessary and sufficient conditions are given in terms of so-called descent 1-cocycles for a C -monoid to be factorized via two C -submonoids. In addition, a criterion is obtained for a C -monoid to be a C -group, from which the characterization of cocommutative C -bimonoids that are Hopf C -monoids is derived 2025-09-26T11:33:34Z 2025-09-26T11:33:34Z 2025-08-08 journal article Mesablishvili, T.
