Abstract: | The fermionic Fock space is represented by the Wiener chaos. This identification allows one to define fermionic Brownian motion with a probability measure. In the underlying geometrical picture this Brownian motion evolves in the linear space of the generators of the Grassmann algebra which spans the Fock space. More general stochastic processes can be derived with the help of stochastic differential equations. The generalization to supersymmetric processes is based on the Wiener-Grassmann product of Le Jan, an algebraic structure which is adequate to investigate differential operators on Wiener spaces. |
