An R-module M is called Ding projective if there exists an exact sequence ⋯ → P 1 → P 0 → P 0 → P 1 → ⋯ of projective R-modules with M= Ker (P 0 → P 1) such that Hom (-,F) leaves the sequence exact whenever F is a flat R-module. In this paper, we develop some basic properties of such modules. WebSuppose that T = ( A 0 U B) is a formal triangular matrix ring, where A and B are rings and U is a ( B, A )-bimodule.
