[Petr Somberg]

 There is last minute change - the seminar will take place
in the seminar room on the third floor in the front building
of the Math. Institute.

> This is just a remainded of our seminar for today, which
>exceptionally takes its present form in the library (and
>not in Konirna as usual!)

>> Title: Homological reduction of Poisson structures
>> Abstract
>>
>>
>> From Roytenberg-Ševera, we know that Poisson manifolds are in one-to-one
>> correspondence with symplectic NQ-manifolds of degree one.
>> Cattaneo-Zambon further extended this relation to the level of reduction
>> with their graded geometric approach to Poisson reduction. Based on these
>> ideas, we explain how homotopy Poisson structures may arise as
>> homological models for Poisson reduced spaces obtained from more general
>> reduction setups. Our results extend the classical homological
>> formulation of hamiltonian reduction of symplectic and Poisson manifolds
>> due to Kostant-Sternberg and Stasheff.
>> --------------------------------------------------------------
