Conserved charges of non-yangian type for the Frahm-Polychronakos spin chain
P. Mathieu, Y. Xudous
Through an -expansion of the confined Calogero model with spin exchange interactions, we extract a generating function for the involutive conserved charges of the Frahm-Poly…
The Painlevé analysis for N=2 super KdV equations
S. Bourque, P. Mathieu
The Painlevé analysis of a generic multiparameter N=2 extension of the Korteweg-de Vries equation is presented. Unusual aspects of the analysis, pertaining to the presence of two f…
Open problems for the superKdV equations
Pierre Mathieu
After a review of the basic results concerning the supersymmetric extensions of the Korteweg-de Vries equation, with a pedagogical presentation of the superspace techniques…
Fusion bases for affine Lie algebras
Luc Begin, Chris Cummins, P. Mathieu
Fusion coefficients for affine Lie algebras are fixed by the corresponding tensor-product coefficients and a set of threshold levels. It is shown how the information concerning the…
