On zero subrings and periodic subrings

Howard E. Bell

International Journal of Mathematics and Mathematical Sciences, 2001, vol. 28, 1-5

Abstract:

We give new proofs of two theorems on rings in which every zero subring is finite; and we apply these theorems to obtain a necessary and sufficient condition for an infinite ring with periodic additive group to have an infinite periodic subring.
