Abstract :In this paper, some characterizations of partial isometries, normal elements and strongly $EP$ elements are given by the construction of $EP$ elements. At the same time, the partial isometry elements are characterized by the existence of solutions of equations in rings in a given set, and also by the general form of solutions of given equations.
Keywords : Group inverse, MP invertible element, partial isometry element, EP element, strongly EP element, normal element
