摘要:
We construct under CH many uncountable sets of reals with strong combinatorial properties which are defined in terms of measure and category. All our constructions involve a sequence of countable ZFC-models and a sequence of generics over these models for the appropriate partial ordering. We also construct several uncountable hereditary gamma-sets.
