Abstract

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