Abstract:( LÓDŹ) 0. Introduction. The main aim of this paper is to answer the question of when βX × βY is the Wallman compactification of X × Y with respect to the normal base consisting of the zero-sets of all those continuous real functions defined on X ×Y which are continuously extendable over βX ×βY . In passing, we shall obtain several new conditions which are necessary and sufficient for X × Y to be pseudocompact.To provide a framework for our discussion, let us recall that a normal base D for a Tikhonov space… Show more
