Seminar organizer’s toolbox
Frank Tall has worked in many areas of settheoretic topology and set theory.
His current interests involve
a) applying forcing, large cardinals, selection principles, and topological games to classic problems concerning Lindelof
spaces,
b) applying models of form PFA(S)[S] to classic problems about paracompactness and metrizability in locally compact spaces, where a model is of form PFA(S)[S] if it is obtained by forcing with a coherent Souslin tree S over a model of
PFA restricted to those posets that preserve S. Such models are useful because in them hold many consequences of
PFA as well as some consequences of V = L.
Recent and upcoming talks by Franklin Tall
Franklin Tall: Arhangel’skii’s Lindelof points $G_{\delta}$ problem
Place: Fields Institute (Room 210)
Date: October 21st, 2016 (13:3015:00)
Speaker: Franklin Tall
Title: Arhangel’skii’s Lindelof points $G_{\delta}$ problem
Abstract: My claim of a solution was premature. I will discuss the history of the
problem, introduce ndowments and the Mitchell collapse, and prove some results that could lead to a solution. continue reading…
Franklin Tall: Work in progress
Place: Fields Institute (Room 210)
Date: September 23, 2016 (13:3015:00)
Speaker: Franklin Tall, University of Toronto
Title: Work in progress
Abstract: Depending on what I accomplish in the next week, I will either speak on the cardinality of regular Lindelof spaces with points $G_{\delta}$ or else on some connections among spaces satisfying the Baire Category Theorem, logics satisfying the Omitting Types Theorem, and nonmeager Pfilters. continue reading…
Franklin Tall: Nonmetrizable descriptive set theory, generalized metric spaces, and selection principles
Place: Fields Institute (Room 210)
Date: March 4th, 2016 (13:3015:00)
Speaker: Franklin Tall
Title: Nonmetrizable descriptive set theory, generalized metric spaces, and selection principles
Abstract: This is a continuation of my most recent talk, but knowledge of that one is not required. continue reading…
Franklin Tall: Definable Versions of Hurewicz’s Conjecture that Menger Spaces are Sigmacompact
Place: Fields Institute (Room 210)
Date: January 29 , 2016 (13:3015:00)
Speaker: Franklin Tall
Title: Definable Versions of Hurewicz’s Conjecture that Menger Spaces are Sigmacompact
Abstract: Hurewicz’s conjecture that Menger spaces are sigmacompact is false; it is true for analytic subspaces of Polish spaces and undecidable for other definable subspaces of Polish spaces. continue reading…

Abstract:
We continue with Alan Dow’s proof that PFA(S)[S] implies every first countable perfect preimage of $\omega_1$ includes a copy of $\omega_1$. continue reading…

Date: July 3rd (13:30 15:00)
Speaker: Franklin Tall
