## Geometry and quantization of moduli spaces of Higgs bundles

The ubiquity of moduli spaces of semi-stable higgs bundles on a smooth projective curve both in mathematics and physics is rather impressive. These moduli spaces have proven to be grounds of extremely fruitful interaction between the two disciplines. As an example, the techniques developed by physicists to quantize a symplectic manifold and to quantize a com- pletely integrable Hamiltonian system when applied to these moduli spaces yield remarkable mathematical results.
