ZERO BIDIMENSION, AND ALMOST DIMENSION OF TOPOLOGICAL SPACES

on the occasion of his 80th birthday Abstract. The sum theorem is proved and its corollaries are given for a countable family of zero-dimensional (in the sense of small and large induc-tive bidimensions) p-closed sets, using a new bitopological notion of relative normality whose topological correspondence is also new. The notion of al-most n-dimensionality is considered from the bitopological point of view
