 DMS Set Theoretic Topology Seminar Time: Sep 18, 2017 (03:00 PM) Location: Parker Hall 224 Details: Speaker: Ziqin Feng ﻿continues Title: Spaces with $$\mathbb{Q}$$-dominated diagonal Abstract:  A space is dominated by $$M$$ if there is a $$\mathcal{K}(M)$$-directed compact cover, where $$\mathcal{K}(M)$$ is the set of compact subsets of the space $$M$$.   We will show that, under $$\mathfrak{b}>\omega_1$$, a compact space with a $$\mathbb{Q}$$-dominated diagonal is metrizable (where $$\mathbb{Q}$$ is the space of rational numbers).  ﻿
