A theorem for metrizability of a topological space
Since Alexandroff and Urysohn's work various theorems concern- ing metrizability of a topological space were gotten by many mathe- maticians, but their methods of proofs are, in general, various and rather complicated.The purpose of this brief note is to prove a theorem for metrizability, which will contain a large number …
