Distances en geometrie non commutative
Pierre Martinetti
Cette these etudie l'aspect metrique de la geometrie non commutative a travers la formulation de Connes de la distance entre etats d'une algebre. Sont etudies des exemples d'espace…

Discrete Kaluza-Klein from scalar fluctuations in noncommutative geometry
P. Martinetti, R. Wulkenhaar
We compute the metric associated to noncommutative spaces described by a tensor product of spectral triples. Well known results of the two-sheets model (distance on a sheet, distan…

Wave-Function renormalization and the Hopf algebra of Connes and Kreimer
Florian Girelli, Thomas Krajewski, Pierre Martinetti
In this talk, we show how the Connes-Kreimer Hopf algebra morphism can be extended when taking into account the wave-function renormalization. This leads us to a semi-direct produc…
