The Casson Invariant and Feynman diagrams
Vendredi, 9 Novembre, 2018 - 10:30
Résumé :
I will review the definition of the Casson-Walker invariant of rational homology spheres and its connection to Feynman graphs. Then I will discuss some recent computations involving the cutting and gluing of these diagrams, and some conjectures that result from these computations.
