Path integral formulation of noncommutative superspace in IKKT matrix model

We propose a physical interpretation of our novel fermionic solution for the IKKT matrix model which obtained in our previous paper hep-th/0307236. We extend the configuration space of bosonic field to supernumbers space and obtain the noncommutative parameter which is not bi-grassmann but an ordinary number. This establishes the connection between Seiberg’s noncommutative superspace and our solution of the IKKT matrix model.
