We generalize the Kodaira Embedding Theorem and Chow's Theorem to the context of families of complex supermanifolds. In particular, we show that every family of super Riemann surfaces is a family of projective superalgebraic varieties.

The main goal of this paper is to introduce a set of conjectures on the relations in the tautological rings. In particular, the framework gives an efficient algorithm to calculate all tautological equations using only finite dimensional linear algebra. Other applications are also indicated.

A counterpart of the modular double for quantum superalgebra Uq(osp(1\2)) is constructed by means of supersymmetric quantum mechanics. We also construct the R-matrix operator acting in the corresponding representations, which is expressed via quantum dilogarithm.
