摘要:We study when the kernel of a complete hereditary cotorsion pair is the additive closure of a tilting module. As a consequence, we characterize when the little finitistic dimension is finite for a left Noetherian ring. Moreover, some equivalent formulations for a Wakamatsu tilting module to be a tilting module are given.

摘要:We study Tate–Vogel cohomology of complexes by applying the model structure induced by a complete hereditary cotorsion pair of modules. It is proved that vanishing of  Tate–Vogel cohomology characterizes the finiteness of the little finitistic dimension.
