Abstract: We consider the representation space of a compact surface, that is the spaceof morphisms from the fundamental group to SU2 up to conjugation. We showthat the trace functions associated to multicurves on the surface are linearlyindependent as functions on the representation space. The proof relies on theFourier decomposition of the trace functions with respect to some torus actionprovided by a pants decomposition. Consequently the space of trace functions isisomorphic to the skein algebra at A=-1 of the thickened surface.
