Borel distinguishing number
<p><b>Abstract</b>: In broadest sense, descriptive graph
combinatorics is the study of "definable" graphs on
Polish spaces that incorporates the descriptive set
theoretic point of view into the graph-theoretic point
of view. This is usually done by demanding various
graph-theoretic objects such as edge relations,
colorings, automorphisms to have
topological/measure-theoretic properties such as being
Borel, projective, continuous, closed and asking to
what extent classical results of graph theory
generalize to measurable setting. Over the last two
decades, numerous interesting results have been proven
which demonstrate that this point of view is more than
a mere specialization that lead to fruitful ideas. In
the first half of this talk, after recalling some
basic descriptive set theoretic notions, we shall give
a brief overview of some fundamental results in
descriptive graph combinatorics. In the second half of
this talk, we will cover some new results regarding
Borel distinguishing numbers. The results in the
second half are from a joint ongoing work with Onur
Bilge.</p>
