A Generalization of Homological Dimensions,projective modules for any non-negative integers . and any Wakamatsu tilting module ., and then give some of their characterizations. In particular, for a tilting module . which satisfies an F.S. condition such that Add . is closed under submodules, we show that if . belongs to Prod ., then submodul

Additive Rank Functions and Chain Conditions,e mean a mapping ρ from mod-. to the set ℕ of non-negative integers such that, for every exact sequence 0 → . → . → . → 0 in mod-., we have ρ(.)=ρ(.)+ρ(.). In this note we exhibit a relationship between additive rank functions on mod-. and ascending chain conditions of a certain type. Specifically,

,A Note on (α, β)-higher Derivations and their Extensions to Modules of Quotients,gher derivation and demonstrate that a filter of a hereditary torsion theory that is invariant for α and β is (α, β)-higher derivation invariant. As a consequence, any higher derivation can be extended from a module to its module of quotients. Then, we show that any higher derivation extended to a m
