I am editor of the Special Issue dedicated to the proceedings of the
conference ``Physics and Mathematics'' held at IHES, november 2005,
Lett. Math. Phys. 78 vol.3 (2006).
- I wrote the notes for the lectures From index theory to non commutative
geometry, given by N. Teleman at Les Houches summer school of theoretical
physics 1995 and published in the Proceedings, (1998) 787-844.
