Julian Külshammer (Uppsala), Dual extensions - bocs perspectives

Abstract:
We discuss Changchang Xi's notion of the dual extension of two directed algebras, which is a certain class of quasi-hereditary algebras as well as an alternative characterisation using the language of bocses, that is coring objects is a category of bimodules. This is based on joint work in progress with Kostiantyn Iusenko and John MacQuarrie as well as on work of my PhD student Markus Thuresson.
