Higher commutator conditions for extensions in Mal'tsev categories
Arnaud Duvieusart, Marino Gran
We define a Galois structure on the category of pairs of equivalence relations in an exact Mal'tsev category, and characterize central and double central extensions in terms of hig…
Some remarks on protolocalizations and protoadditive reflections
Maria Manuel Clementino, Marino Gran, George Janelidze
We investigate additional properties of protolocalizations, introduced and studied by F. Borceux, M. M. Clementino, M. Gran, and L. Sousa, and of protoadditive reflections, introdu…
Split extension classifiers in the category of cocommutative Hopf algebras
Marino Gran, Gabriel Kadjo, Joost Vercruysse
We describe the split extension classifiers in the semi-abelian category of cocommutative Hopf algebras over an algebraically closed field of characteristic zero. The categorical n…
Some remarks on connectors and groupoids in Goursat categories
Marino Gran, Diana Rodelo, Idriss Tchoffo Nguefeu
We prove that connectors are stable under quotients in any (regular) Goursat category. As a consequence, the category of connectors in is a…
