Gelfand ring
In mathematics, a Gelfand ring is an associative ring R with identity such that if I and J are distinct right ideals then there are elements i and j such that iRj=0, i is not in I, and j is not in J. introduced them as rings for which one could prove a generalization of Gelfand duality, and named them after Israel Gelfand.
