Carvalho, University of Hradec Kralove<br>Title: Homological reduction of Poisson structures<br>Abstract<br><br><br>From Roytenberg-Ševera, we know that Poisson manifolds are in one-to-one<br>correspondence with symplectic NQ-manifolds of degree one.<br>Cattaneo-Zambon further extended this relation to the level of reduction<br>with their graded geometric approach to Poisson reduction. Based on these<br>ideas, we explain how homotopy Poisson structures may arise as<br>homological models for Poisson reduced spaces obtained from more general<br>reduction setups. Our results extend the classical homological<br>formulation of hamiltonian reduction of symplectic and Poisson manifolds<br>due to Kostant-Sternberg and Stasheff.<hr>We shall open the seminar room+ ZOOM at 13.15 for coffee and close the<br>room at 15:00<br><br><br>Join Zoom Meeting<br><br><br><br><a href="https://cesnet.zoom.us/j/99598413922?pwd=YXNFbk50aVhleXhWSGtISFViLytRU9">https://cesnet.zoom.us/j/99598413922?pwd=YXNFbk50aVhleXhWSGtISFViLytRU9</a><br><br><br><br>MeetingID:99598413922<br><br><br><br>Passcode:Galois<br><br><br><br><br><br><br><br><br><br>For more information see the seminar web page at<br><a href="https://www.math.cas.cz/index.php/events/seminar/16">https://www.math.cas.cz/index.php/events/seminar/16</a><br><br><br>Cohomology in algebra, geometry, physics and statistics mailing list<br>phk_seminar@math.cas.cz<br><a href="https://list.math.cas.cz/listinfo/phk_seminar@math.cas.cz">https://list.math.cas.cz/listinfo/phk_seminar@math.cas.cz</a><hr>phk_seminar mailing list phk_seminar@math.cas.cz<br><a href="https://list.math.cas.cz/listinfo/phk_seminar">https://list.math.cas.cz/listinfo/phk_seminar</a><br><br><br></div></blockquote><div dir="auto"><hr>phk_seminar mailing list<br>phk_seminar@math.cas.cz<br><a href="https://list.math.cas.cz/listinfo/phk_seminar">https://list.math.cas.cz/listinfo/phk_seminar</a><br></div></pre></blockquote></div></body></html>
