Hepimizi sarsan ve üzen Maraş Bölgesinde meydana gelmiş olan korkunç 
depremde yakınlarını
kaybeden, depremden zarar gören herkese başsağlığı ve sabır dileklerimi 
gönderiyorum.

Aşağıda düzenli olarak tertiplediğimiz Feza Gürsey Merkezi Yüksek 
Yapılar Seminer Serimizin
21 Şubat tarihinde yapılması planlanan seminer ilanını bulacaksınız. 
Zoom bağlantı detayları
yarın akşam ilan edilecektir.

--FGC-Higher Structures esearch Group Seminars--

Because of the massive earthquake in the Maras Region, we have 
re-scheduled our
FGC-Higher Structures Research Seminar dated February 14 2023 to 
February 21 2023.

Once again we would like to express our most sincere condolences and 
share the grief
and sadness that this has caused to the people of the South East Turkey 
and Syria...

This week our speaker is Yusuf Barış Kartal from the University of 
Edinburgh, and the
details of his talk are as follows:

Title: Frobenius operators in symplectic topology

Abstract:
One can define the Frobenius operator on a commutative ring of 
characteristic p as the
p th power operation, and this has generalizations to a larger class of 
commutative rings,
and even to topological spaces and spectra. Spectra with circle actions 
and Frobenius
operators are called cyclotomic spectra. The simplest example is the 
free loop space,
and important examples arise in algebraic and arithmetic geometry as 
topological Hochschild
homology of rings and categories. By topological reasons and mirror 
symmetry, it is natural
to expect such a structure to arise in symplectic topology-- more 
precisely in closed string
Floer theory''. In this talk, we will explain how to construct such 
spectra using Hamiltonian
Floer theory, i.e. by using holomorphic cylinders in symplectic 
manifolds. Joint work in
progress with Laurent Cote.

Zoom link details: TBA.
