BILKENT
ALGEBRA-TOPOLOGY SEMINAR

"Kalinin's spectral sequence"

By

Alex Degtyarev

(Bilkent University)

Abstract: We will discuss a stabilized
1-graded version of the Borel-Serre spectral
sequence, which we call Kalinin's spectral sequence. Amongst the advantages of
the stabilization are finite dimension, a clear geometric description of the
differentials and the convergence, Poincar\'e duality
(in the case of manifolds), the ease of computation, etc. Examples and
applications to real algebraic geometry will be considered.

Tea and cookies will be served after the
seminar.
