This thesis is divided into two parts. 1. Conformally equivariant quantization of supercotangent bundles. We mean by quantization of the supercotangent bundle of a manifold M, a linear isomorphism between the space of superfunctions, fiberwise polynomial, and the space of differential operators acting on spinors over M. In the case of conformally flat manifolds (M,g), we prove the existence and uniqueness of such a quantization, demanding equivariance with respect to the action of conformal transformations of M. 2. On the projective geometry of the supercircle: a unified construction of the super cross-ratio and Schwarzian derivative. We establish, for three supergroups acting on the supercircle, a correspondence between the supergroup, t...
