An alternative construction of Kontsevich-Kuperberg-Thurston invariant
Vendredi, 23 Janvier, 2015 - 10:30
Résumé : 
The Kontsevich-Kuperberg-Thurston invariant of rational homology 3-spheres is a variation of the Chern-Simons perturbation theory.
In this talk, we give an alternative construction of this invariant by using vector fields.
As an application of this construction, we prove that K. Fukaya and T. Watanabe's Morse homotopy invariant coincides with the Kontsevich-Kuperberg-Thurston invariant.
