  • Published:
Journal of Mathematical Sciences Aims and scope Submit manuscript

Abstract

The first part of the paper is concerned with conditions under which the inequality dim X × Y ≤ dim X + dim Y and similar inequalities for infinite topological products hold. The second part contains examples of spaces such that the sums of their dimensions are smaller than the dimensions of their products.
