Outline of Final Research Achievements

A prehomogeneous vector space of commutative parabolic type is determined by a certain pair of a simple algebraic group G and its maximal parabolic subgroup P, We studied a relation between automorphic pairs of distributions on a prehomogeneous vector space of this type and (quasi-) automorphic distribution vectors belonging to degenerate principal series representations of G using associated zeta functions. The case G = SL(2) was analyzed in detail and as an application we obtained a Weil-tye converse theorem for Maass wave forms. We applied the theory of automorphic pairs to quadratic mappings and constructed zeta functions associated to Clifford quartic forms. It is a conjecture that the zeta functions coincide with the Koecher-Maass zeta functions of Eisenstein series of orthogonal groups. We obtained partial affirmative results on the conjecture.
