Relative contravariantly finite subcategories and relative tilting modules
Abstract
Let be a finite dimensional algebra over an algebraically closed field . Let be a tilting -module and be the endomorphism algebra of . In this paper, we consider the correspondence between the tilting -modules and the tilting -modules, and we prove that there is a one-one correspondence between the basic -tilting -modules in and the basic tilting -modules in . Moreover, we show that there is a one-one correspondence between the -contravariantly finite -resolving subcategories of and the basic -tilting -modules contained in . As an application, we show that there is a one-one correspondence between the basic tilting -modules in and the basic tilting -modules in if is a -Gorenstein algebra or a -replicated algebra over a finite dimensional hereditary algebra.
