Title:
Equivariant Methods in Discrete Geometry: Problems and Progress
Speaker:
Abstract:
In this lecture, I will discuss three different problems from Discrete Geometry,
the Topological Tverberg Problem,
the Colored Tverberg Problem, and
the Grünbaum Hyperplane Problem.
These problems have many things in common:
They are easy to state, and may look harmless,
They have very nice and classical configuration spaces,
they may be attacked by ``Equivariant Obstruction Theory'',
this solves the problems --- but only partially,
which leads us to ask more questions, look for new tools ...
and this yields surprising new results.
