Abstract

The Continuum Hypothesis implies an Erdö-Sierpi&nacute;ski like duality between the ideal of first category subsets of &reals; &naturals; , and the ideal of countable dimensional subsets of &reals; &naturals; . The algebraic sum of a Hurewicz subset - a dimension theoretic analogue of Sierpinski sets and Lusin sets - of &reals; &naturals; with any compactly countable dimensional subset of &reals; &naturals; has first category.
