AI 中文摘要
我们的主要结果是构造了一类H,由道路连通、局部连通、紧致豪斯多夫空间组成,使得(i)若X,Y是H中不同的空间,则不存在从X到Y的连续单射;(ii)对于不小于连续统基数的每个基数k,H包含2^k个权重为k且大小为k的空间;(iii)若k,l是无限基数且l不大于k,则H包含2^k个权重为k且大小为k^l的空间;(iv)H中的可度量化连续统是平面的子空间。
英文摘要
Our main result is a construction of a class H of pathwise connected, locally connected, compact Hausdorff spaces such that (i) if X,Y are distinct spaces in H then a continuous, injective mapping from X to Y does not exist; (ii) H contains 2^k spaces of weight k and size k for every cardinal number k not smaller than the cardinality of the continuum; (iii) if k,l are infinite cardinals and l is not greater than k then H contains 2^k spaces of weight k and size k^l; (iv) the metrizable continua in H are subspaces of the plane.
