Let H be a Hilbert space, and let T : H → H be a bounded linear operator with closed range. In this paper, we discuss about the hypo-EP operators with reference to indefinite inner product, which is weaker than the case of EP operators. Moreover, we characterize such operators and some fundamental properties have been established. Keywords Indefinite inner product, range symmetric, hypo normal operators, hypo-EP operators.
