All tilting modules are of countable type

J Šťovíček, J Trlifaj - Bulletin of the London Mathematical …, 2007 - Wiley Online Library
Let R be a ring and T an (infinitely generated) tilting module. Then T is of countable type; that
is, there is a set, 𝒞, of modules possessing a projective resolution consisting of countably …

Infinitely generated Gorenstein tilting modules
