摘要
We prove that, for every cardinal number , there exists a metrizable space with such that for every pair of quasiorders , on a set with satisfying the implication there exists a system of non-homeomorphic clopen subsets of with the following properties: (1) if and only if is homeomorphic to a clopen subset of , (2) implies that is homeomorphic to a closed subset of and (3) implies that there is no one-to-one continuous map of into .
