*"A Tate Cohomology version of the Lyndon-Hochschild-Serre Spectral
Sequence"*


 Abstract:
In the first part of this talk, I will sketch the ideas and definitions of
Cohomology for Profinite Groups and I will point out the differences with
the usual Group Cohomology. In the second part, I will introduce an
extension of the Hochschild-Serre Spectral Sequence for a profinite group G
and an open subgroup H that also takes into account the Tate Cohomology of
the group G/H. Under certain conditions, this spectral sequence converges
to zero. In the case of a
finite Galois extension of local fields, with Prof. David Vauclair of the
University of Caen Basse-Normandie, we proved that the results obtained
provide a different interpretation of the Reciprocity Map of the Local
Class Field Theory.
