报告题目:One type of twisted tensor products: Generalized Ore extension

摘要:We study homological properties of twisted tensor products of connected graded algebras. By focusing first on the Ext-algebras of twisted tensor products with a certain form of twisting maps, we show those Ext-algebras are also twisted tensor products, and describe the twisting maps for such Ext-algebras explicitly. With those preparations, we describe Nakayama automorphisms of twisted tensor products of oetherian Artin-Schelter regular algebras.
