Abstract
We study a generalization of tilting modules to modules of possibly infinite projective dimension, introduced by Wakamatsu in [J. Algebra 114 (1988) 106–114]. In particular, we characterize these modules in terms of suitable subcategories of finitely generated modules and in terms of cotorsion theories.
