Exact Borel subalgebras of tensor algebras of quasi-hereditary algebras

Anna Rodriguez Rasmussen

Given two quasi-hereditary algebras, their tensor product is quasi-hereditary. In this article, we show that given two exact Borel subalgebras for these quasi-hereditary algebras,…

Exact Borel subalgebras of quasi-hereditary monomial algebras

Anna Rodriguez Rasmussen

Green and Schroll give an easy criterion for a monomial algebra $A$ to be quasi-hereditary with respect to some partial order $\leq_{A}$ . A natural follow-up question is under which…

Uniqueness up to Inner Automorphism of Regular Exact Borel Subalgebras

Anna Rodriguez Rasmussen

Külshammer, König and Ovsienko proved that for any quasi-hereditary algebra $(A, \leq_{A})$ there exists a Morita equivalent quasi-hereditary algebra $(R, \leq_{R})$ containing a basic…
