Abstract
In this paper, we present intriguing findings that characterize both the closed (unbounded) and bounded EP operators on Hilbert spaces. Additionally, we demonstrate the result , where is a bounded EP operator, and represent the reduced minimum modulus and the spectral radius of , respectively.
