摘要:Infinitely generated tilting modules provide completely new features in the tilting theory of algebras. For instance, recollements of triangulated categories in the sense of Beilinson-Bernstein-Deligne enter into the play. In this talk, we consider the derived category of the endomorphism ring of a good tilting module (not necessarily finitely generated) and show that the kernel of the total left-derived tensor functor induced by a good tilting module is always triangle equivalent to the derived category of a symmetric subcategory of a module category. Also, we give a construction of 2-good tilting modules over commutative Gorenstein rings, and describe the symmetric subcategories associated to these tilting modules. The contents of the talk are taken from a joint work with Hongxing Chen.
