Kunneth formulas for Cotor
A. Salch
We investigate the question of how to compute the cotensor product, and more generally the derived cotensor (i.e., Cotor) groups, of a tensor product of comodules. In particular, w…

Milnor-Moore theorems for bialgebras in characteristic zero
Joey Beauvais-Feisthauer, Yatin Patel, Andrew Salch
Over fields of characteristic zero, we construct equivalences between certain categories of bialgebras which are generated by grouplikes and generalized primitives, and certain cat…

Graded comodule categories with enough projectives
A. Salch
It is well-known that the category of comodules over a flat Hopf algebroid is abelian but typically fails to have enough projectives, and more generally, the category of graded com…
