Research areas

Commutative Ring Theory. Most of my work is devoted to phi-Commutative Rings: a class of commutative rings that I definedandit contains the class of integral domains. My work focuses onphi-Valuation domains, phi-Pseudo-Valuation rings, phi-Integral Closure of rings, phi-Noetherian rings, phi-Prufer rings, phi-Dedekind rings, and phi-Krul rings. Other interests includen-Absorbing Ideals, Zero-divisor graphs and Total graphs of Commutative rings, and Pi-regular rings
