Abstract
In this paper, we explore the concept of finite direct projective covers and envelopes. We identify the conditions under which a projective cover of a module is finite direct projective cover. Additionally, we provide descriptions of modules with finite direct projective covers in the context of semi-perfect and semi-regular rings. We also discuss the properties of finite direct projective envelopes.
Keywords: Finite direct projective module, semi-perfect ring, semi-regular ring.
