Infinite dimensional covariance and non relativistic limits in time dependent theories
Antoine D. Coste
We give some account of investigations for the role of infinite dimensional algebras in time dependent systems.
Generalised Fermat Hypermaps and Galois Orbits
Antoine D. Coste, Gareth A. Jones, Manfred Streit +1
We consider families of quasiplatonic Riemann surfaces characterised by the fact that -- as in the case of Fermat curves of exponent -- their underlying regular (Walsh) hyperma…
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…
Finite Group Modular Data
A. Coste, T. Gannon, Ph. Ruelle
In a remarkable variety of contexts appears the modular data associated to finite groups. And yet, compared to the well-understood affine algebra modular data, the general properti…
