WHAT:
Judy Roitman
of the Department of Mathematics, University of Kansas,
Lawrence, will give a talk on
A Survey of the S and L Space Problem
ABSTRACT:
The problem of S and L spaces is one of the two paradigm problems of
set theoretic topology (the other being the normal Moore space problem). It is a paradigm
problem because
(a) it grows out of very basic questions about
characterizations of
common mathematical objects, in this case the real numbers;
(b) it has led to important developments in set theory;
(c) it has deep connections to other problems in both set theory
and topology.
In addition, it has the virtue that one of the most important
questions associated with it --- is there an L space? --- remains open. This talk will be
a survey of some of the developments in the area of S and L spaces, as a way of
introducing set theory and set theoretic topology to a general audience.
