Martedì 27 Febbraio alle ore 15:30 presso l’Aula 3014 nell'Edificio U5, il Prof. Batu Güneysu (Technische Universität Chemnitz) terrà il seguente seminario

Title: Fermions and perturbation theory of strongly continuous semigroups

Abstract: In this talk I will explain an algebraic machinery based on Fermionic integration, which basically allows to rewrite expressions of the form

 ꭍ_tσn e^−s1HP₁e^{−(s2−s1)H}P₂…e^{−(sn−sn−1)H}P_ne^−(t−sn)H ds₁…ds_n, t ≥ 0,

as strongly continuous semigroups. Here, H ≥ 0 is an unbounded selfadjoint operator and each P_j is an unbounded possibly non-selfadjoint operator. Applications to noncommutative geometry (and if time admits: loop space geometry) will also be presented.

Tutti gli interessati sono invitati a partecipare
