In the past few decades, researchers have found that studying modules using
endomorphisms is a powerful and useful tool. This has led to valuable works in this field …

In this article, we study the notion of closed Rickart modules. A right R-module M is said to
be closed Rickart if, for each, is a closed submodule of M. Closed Rickart modules is a …

We introduce the notions of T-dual Rickart and strongly T-dual Rickart modules. We provide
several characterizations and investigate properties of each of these concepts. It is shown …

Let R be a commutative ring with identity and M be an R-module. Let Z2 (M) be the second
singular submodule of M. In this research we introduce the concept of Goldie Pure Rickart …

Let R be a commutative ring with identity and M be an R-module. In this paper we
introducethe dual concepts of Pure Rickart modules and Pure𝜋-Rickart modulesas a …

Let 𝑀 be a right module over an arbitrary ring 𝑅 with identity and S End 𝑀. In this work, the
coclosed rickart modules as a generalization of rickart modules is given. We say a module 𝑀 …

In this paper, we introduce a dual purely Rickart modules as a dual concept of purely Rickart
modules and a proper generalization to dual Rickart modules. Some characterizations are …

In a previous work, Ali and Ghawi studied closed Rickart modules. The main purpose of this
paper is to define and study the properties of y-closed Rickart modules. We prove that, Let …

Abstract Gangyong Lee, S. Tariq Rizvi, and Cosmin S. Roman studied Rickart modules. The
main purpose of this paper is to develop the properties of Rickart modules. We prove that …
