Tilting pairs and Wakamatsu tilting subcategories over triangular matrix algebras

Y Zhang, Y Ma, T Zhao - Georgian Mathematical Journal, 2023 - degruyter.com
Let A and B be Artin algebras and let M be an (A, B)-bimodule with MA and MB finitely
generated. In this paper, we construct tilting pairs of subcategories and Wakamatsu tilting …

Homological aspects of formal triangular matrix rings

MAO Lixin - Hacettepe Journal of Mathematics and Statistics - dergipark.org.tr
Let $ T=\biggl (\begin {matrix} A&0\\U&B\end {matrix}\biggr) $ be a formal triangular matrix
ring, where $ A $ and $ B $ are rings and $ U $ is a $(B, A) $-bimodule. We first give some …
