报告摘要：Finite-dimensional algebras are typically wild, making classification of their modules intractable. Instead, we study torsion pairs in mod-
, forming a lattice tors() that reveals structural information. For -tilting finite algebras, torsion pairs are parameterized by -tilting modules and bricks. In general cases, infinite-dimensional cosilting modules extend this classification. We present an analogue of Asai's correspondence for infinite-dimensional modules and non-functorially finite torsion pairs, based on joint work with Nasr-Isfahani.
报告人简介：Ramin Ebrahimi is a postdoc in Institute for research in fundamental science (IPM) in Iran. He received his PhD in mathematics in 2020 in the universityof Isfahan, under supervision of Dr Alireza Nasr-Isfahani. His research field concernsthe representation theory of algebras, homological algebra and derived categories. Hehas some research papers in some prestigious journals such as International Mathematics Research Notices, Bulletin of London Mathematical Society, The Quarterly Journal of Mathematics and Journal of Algebra.
