Titre  Mtheory on deformed SasakiEinstein manifolds 
Résumé  Compactifications of Mtheory down to AdS4 are known to arise from Sasaki Einstein internal spaces. The latter can be viewed as links around isolated CalabiYau conical singularities, whose deformations can be described algebraically in a well established way. In this talk, I will present work in progress on the construction of the possible deformations of the link away from the SasakiEinstein metric, using the deformations of the CalabiYau cone. This provides a realisation of a class of SU(3) structure manifolds satisfying the conditions postulated in the standard treatments of Mtheory compactifications on such manifolds. The result is a concrete proposal for obtaining four dimensional N=2 supergravity models with gauged hypermultiplets from deformations of regular SasakiEinstein manifolds.
