Location: ZOOM |
Details: Speaker: Dr. Ziqin Feng Title: ZFC, Posets, and Metrization
Abstract: I will briefly introduce one of the foundations of modern mathematics, Zermelo-Fraenkel set theory, i.e., ZFC. Then I will discuss one of recent metrization results in topology which is independent of ZFC. In fact, we show that when \(\omega_1<\mathfrak{b}\), a compact space is metrizable if the local base at each point is a Tukey quotient of the collection of compacts sets in a Polish space. The result doesn't hold when \(\omega_1=\mathfrak{b}\). This answers a recently-published open question. Below is the Zoom information. You can simply use Dr. Cao's Zoom ID 869 331 4103 to sign in.
