Abstract: The orbit structure of real forms G of a complex semisimple group G on a G-flag manifold Z was analyzed by J. A. Wolf in [Wolf]. One of his results was that each open orbit DZ contains a unique complex K-orbit C0 where K is a maximal compact subgroup of G. C0 is called the base cycle and the connected component M of all its G-translates contained in D is called the cycle space of D. D and M fit into a double fibration and the associated Doubel Fibration Transform yields numerous natural unitary representations of the real reductive group G. In this talk I will discuss which problems and obstacles arise when one tries to generalize the notion of cycle and the Double Fibration Transform to a supergeometric setting and offer some ideas on how to solve these issues.
