buondì, concludiamo oggi il ciclo dei seminari di geometria di quest'anno; come sempre, alle 16 in aula seminari. a presto, Bruno ------------ MERCOLEDI' 16 LUGLIO 2014 16:00-17:00, Sala Seminari (Dip. Matematica) SEMINARI DI GEOMETRIA A Morse-Bott approach to the Triangulation conjecture Francesco Lin (MIT Boston) Manolescu has recently given a negative answer to the celebrated Triangulation conjecture (first stated by Kneser in 1924). His disproof relies on the construction of a new invariant of spin rational homology three spheres obtained by studying the Seiberg-Witten equations from a homotopy-theoretic point of view. In the present talk we discuss how to construct the analoguous invariants in the Morse-theoretic framework of Kronheimer and Mrowka's monopole Floer homology. This approach works on every three manifold and is functorial under cobordisms.
