- * Witness set. Study of the representations of the space F2^n times Jw where Jw is the Johnson space under the action of the hyperoctaedral group. Numerical construction of the zonal functions. SDP program and first bounds on the size of a w-witness set. Bounds turns out to be sharp. (Nov 10 -Feb 2010)+  ​* Witness set.
