Cotilting

Tilting and cotilting theory has its origin in the context of finitely generated modules over finite dimensional algebras. The theory studied equivalences between subcategories of module categories over two algebras and was in essence a generalization of Morita Theory. WebIn §2 and §3, we studyinfinitely generated tilting and cotilting modules, and characterize the induced tilt-ing and cotilting cotorsion pairs. §4 deals with tilting classes of finite type andcotilting classes of cofinite type, and with their classification over particular rings.Finally, §5 relates tilting approximations to the first ...

In particular, we show that a large cotilting module is minimal if and only if it has an adic module as a direct summand. Secondly, we discuss the behavior of minimality under ring extensions.
