Renormalization group flow of -invariant general sextic tensor model
Gaetan Bardy, Thomas Krajewski, Thomas Muller +1
We compute the beta functions for the -invariant general sextic tensor model up to cubic order in the coupling constant, and at leading order in the expansion. Our me…
Large- limit of -invariant general sextic tensor model
Gaetan Bardy, Thomas Krajewski, Thomas Muller +1
We study a sextic tensor model where the interaction terms are given by all -invariant bubbles. The class of invariants studied here is thus a larger one that the class of…
Quasi-quantum groups from Kalb-Ramond fields and magnetic amplitudes for strings on orbifolds
J. -H. Jureit, T. Krajewski
We present the general form of the operators that lift the group action on the twisted sectors of a bosonic string on an orbifold , in the presence of a Kalb-Ramond fie…
An algebraic Birkhoff decomposition for the continuous renormalization group
F. Girelli, T. Krajewski, P. Martinetti
This paper aims at presenting the first steps towards a formulation of the Exact Renormalization Group Equation in the Hopf algebra setting of Connes and Kreimer. It mostly deals w…
Distances in Finite Spaces from Noncommutative Geometry
B. Iochum, T. Krajewski, P. Martinetti
Following the general principles of noncommutative geometry, it is possible to define a metric on the space of pure states of the noncommutative algebra generated by the coordinate…
Perturbative quantum gauge fields on the noncommutative torus
T. Krajewski, R. Wulkenhaar
Using standard field theoretical techniques, we survey pure Yang-Mills theory on the noncommutative torus, including Feynman rules and BRS symmetry. Although in general free of any…
