Let R be a topological (Hausdorff) ring such that for each a ∊ R, aR and Raare closed subsets of R. We will prove that if the set of non - trivialright (left) zero divisors of R is a non-empty set and the set of all right(left) zero divisors of R is a compact subset of R, then R is a compactring. This theorem has an interesting corollary. Namely, if R is a discretering with a finite number of non - trivial left or right zero divisors thenR is a finite ring (Refer [1]).
