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.
