David Massey – Lê Cycles, Vanishing Cycles, and Thom’s a_f Condition 7 janvier 201323 décembre 2012 adminFrumam Carte non disponible Date/heure Date(s) - 07/01/201315 h 30 min - 16 h 30 min Catégories Pas de Catégories The constancy of the Lê numbers along a submanifold M in a hypersurface V(f) implies that Thom’s a_f condition is satisfied between the ambient stratum and M. I will calculate an example explicitly. Then, I will discuss a generalization of this result that relates the a_f condition to a weak form of constructibility of the vanishing cycles along f of an arbitrary complex of sheaves.
