Quasihereditary algebras with exact Borel subalgebras
2020-12-09
|
|
Speaker: Teresa Conde (Univ. Stuttgart, Germany)
|
Exact Borel subalgebras of quasihereditary algebras emulate the role of "classic" Borel subalgebras of complex semisimple Lie algebras. Not every quasihereditary algebra A has an exact Borel subalgebra. However, a theorem by Koenig, Külshammer and Ovsienko establishes that there...

A new approach to S-protomodular categories
2021-01-05
|
|
Speaker: Tamar Janelidze-Gray (Univ. Cape Town, South Africa)
|
|
We propose a new approach to S-protomodular categories in the sense of D. Bourn, N. Martins-Ferreira, A. Montoli, and M. Sobral. Instead of points (=split epimorphisms) it uses generalized points, which we define as composable pairs of morphisms whose composites are pullback stable regular...
