The Segre embedding of the quantum conformal superspace

In this paper we study the quantum deformation of the super flag Fl(2j0; 2j1; 4j1), and its big cell, describing the complex conformal and Minkowski superspaces respectively. In particular, we realize their projective embedding via a generalization to the super world of the Segre map and we use it to construct a quantum deformation of the super line bundle realizing this embedding. This strategy allows us to obtain a description of the quantum coordinate superring of the super flag that is then naturally equipped with a coaction of the quantum complex conformal supergroup SLq(4j1).
