"Infinite Combinatorial Topology"

** Abstract: **
"Infinite Combinatorial Topology", despite having its roots
back in the Cantor era, is a new field in mathematics.
This field studies, from a combinatorial point of view,
the diagonalization arguments which appear in topological
properties and constructions. Many classical properties
are put into a general framework, and combinatorial methods
are used to obtain new insights into these.
We will give a brief, nontechnical survey of
(a major aspect of) this active field of research: Its roots,
examples of problems and methods used to solve them, and
applications. More technical details and examplese are planned to be given
in more focused seminars.
The field is close enough to the axiomatics so that no prior knowledge
is needed, and we believe that exchange of ideas with mathematicians
working in other fields will prove useful for this field. As much
time as needed will be dedicated for questions and discussions.

Light refreshments will be served in the faculty lounge at 3:30.
