Countable spaces without points of first countability

Ronald Fred Levy

Vol. 70 (1977), No. 2, 391–399
Abstract

In this paper we show that there are 2c non-homeomorphic countable regular spaces, each of which has no point of first countability. Several specific countable regular spaces are shown not to be homeomorphic.
