Counting continua
Abstract
For infinite cardinals let denote the class of all compact Hausdorff spaces of weight and size . So if or . If F is a class of pairwise non-homeomorphic spaces in then F is a set of size not greater than . For every infinite cardinal we construct pairwise non-embeddable pathwise connected spaces in for and for . (If is a strong limit then .) Additionally, for all infinite cardinals with we construct pairwise non-embeddable connected spaces in . Furthermore, for with arbitrary and for certain other pairs we construct pairwise non-embeddable connected, linearly ordered spaces such that whenever is an infinite compact and connected subspace of . On the other hand we prove that there is no space with this property if is of countable cofinality and either or is a strong limit.
