Conformal Field Theories on the Two-Torus and Quotients of SL2(Z)
Antoine Coste, Giovanni Felder
We present remarkable properties of the groups SL2(Z/NZ) which might be useful in detailed studies of some quotients appearing in Conformal Field Theories.
Explicit modular formulae and symmetries of RCFT's I
Antoine Coste
We derive compact formulae for modular transformations of WZ characters. We start with algebra A_1 at positive level k=n-2, for which we can easily provide some description of isom…
Representation Theory of Twisted Group Double
D. Altschuler, A. Coste, J-M. Maillard
This text collects useful results concerning the quasi-Hopf algebra $\D $. We give a review of issues related to its use in conformal theories and physical mathematics. Existence o…
Congruence subgroups and rational conformal field theory
A. Coste, T. Gannon
We address here the question of whether the characters of an RCFT are modular functions for some level N, i.e. whether the representation of the modular group SL_2(Z) coming from a…
