Zero ring

In ring theory, a branch of mathematics, the zero ring or trivial ring is the unique ring (up to isomorphism) consisting of one element. (Less commonly, the term "zero ring" is used to refer to any ring of square zero, i.e., a ring in which xy = 0 for all x and y. This article refers to the one-element ring.)
