Fedosov and Riemannian supermanifolds

Generalizations of symplectic and metric structures for supermanifolds are analyzed. Two types of structures are possible according to the even/odd character of the corresponding quadratic tensors. In the even case, one has a very rich set of geometric structures: even symplectic supermanifolds (or, equivalently, supermanifolds with nondegenerate Poisson structures), even Fedosov supermanifolds, and even Riemannian supermanifolds. The existence of relations among those structures is analyzed in some detail. In the odd case, we show that odd Riemannian and Fedosov supermanifolds are characterized by a scalar curvature tensor. However, odd Riemannian supermanifolds can only have a constant curvature. Supersymmetric extensions of Anti de Sitter spaces are considered.
