A Hamiltonian Path Integral for a Degenerate Parabolic Pseudo-Differential Operator
The symbol of the fundamental solution for a degenerate parabolic pseudo-differential operator of order $m\,(>0)$ can be described in terms of a Hamiltonian path integral. This Hamiltonian path integral converges in the topology of the symbol class $\Sn$ and in the weak topology of the symbol class $\So$.
