DESCRIPTION:Title: <a href="https://researchseminars.org/talk/PHK-cohomolo
 gy-seminar/116/">Homological reduction of Poisson structures</a>\nby Pedro
  H. Carvalho (University of Hradec Kralove) as part of Prague-Hradec Kralo
 ve seminar Cohomology in algebra\, geometry\, physics and statistics\n\n\n
 Abstract\nFrom Roytenberg-Ševera\, we know that Poisson manifolds are in 
 one-to-one correspondence with symplectic NQ-manifolds of degree one. Catt
 aneo-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 mod
 els 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.\n
