Journée-séminaire de combinatoire

(équipe CALIN du LIPN, université Paris-Nord, Villetaneuse)

Le 05 mars 2013 à 10h30 en B107, Axel de Goursac nous parlera de : Weyl quantization of the Heisenberg supergroup and application to combinatorial quantum field theory

Résumé : By using Kirillov's orbits method and Weyl-type quantization on the Heisenberg supergroup, we construct a non-formal deformation quantization of superspaces. We are led by the theory to introduce new notions such as Hilbert superspaces and C*-superalgebras. Then, a noncommutative superspace coming from this deformation yields an interpretation of the renormalizable quantum field theory with harmonic term on the Moyal space.
