Abstract: | Consider a path-integral
which is the solution to a diffusion version of the generalized Schro¨dinger's equation
. Here
, where A is an infinitesimal generator of a strongly continuous Markov Semigroup corresponding to the diffusion process
. For
and V replaced by
one obtains
, which represents a quantum mechanical Hamiltonian corresponding to a particle of mass 1 (in atomic units) subject to interaction with potential V. This paper is concerned with computer calculations of the second eigenvalue of
by generating a large number of trajectories of an ergodic diffusion process. |
