[Turkmath:5792] Feza Gursey Center for Physics and Mathematics-Higher Structures Seminars [no.11][10.25.2022]::Kadri İlker Berktav(Zurich)

[kazimilhan.ikeda]

Dear all,

We would like to announce that Kadri İlker Berktav (Universitat Zurich) 
will give a talk in the
"Higher Structures Webinars" of Feza Gürsey Center for Physics and 
Mathematics.

TITLE: "Geometric structures as stacks and geometric field theories "
ABSTRACT: In this talk, we outline a general framework for geometric 
field theories formulated by
Ludewig and Stoffel. In brief, functorial field theories (FFTs) can be 
formalized as certain functors
from an appropriate bordism category Bord to a suitable target category. 
Atiyah's topological field
theories and Segal's conformal field theories are the two important 
examples of such formulation.
Given an FFT, one can also require the source category to endow with a 
''geometric structure''. Of
course, the meaning of ''geometry'' must be clarified in this new 
context. To introduce geometric field
theories in an appropriate way, therefore, we first explain how to 
define ''geometries'' using the
language of stacks, and then we provide the so-called geometric bordism 
category GBord. Finally, we
give the definition of a geometric field theory as a suitable functor on 
GBord.

DATE & TIME: Tuesday, October 25,2022, 17:00 Istanbul local time (16:00
