Vi ricordo che domani
18 Maggio in Aula Seminari si terrà il seminario di Diego Santoro (SNS
Pisa) dal titolo "L-spaces,
taut foliations and fibered hyperbolic two-bridge links". Di
seguito l'abstract.
Heegaard
Floer homology was defined by Ozsváth and Szabó in the early 2000s. It consists of a package of invariants of closed oriented 3-manifolds and it has found many important and profound applications in low dimensional topology. I will introduce the L-space conjecture,
that boldly predicts strong connections among properties relating Heegaard Floer homology, foliations and the fundamental group of an irreducible rational homology 3-sphere. I will then state a result concerning this conjecture for manifolds that arise as
surgeries on fibered hyperbolic two-bridge links. We will also see how to apply this result to deduce that all non-meridional surgeries on Whitehead doubles of a non-trivial knot support coorientable taut foliations.
Ricordiamo che le informazioni sui prossimi seminari si trovano sul sito.
Il seminario successivo sarà Giovedì 01 Giugno in Aula Seminari alle
11: avremo Andrew Lobb (Durham University),
e il titolo del talk sarà "Four-sided pegs fitting round holes fit all smooth holes".
Vi aspettiamo!
Buona giornata,
Alice, Filippo e Giuseppe
