An isomorphism theorem which establishes a relation between a Gaussian random field associated with a symmetric Markov process and local times for the process is proved. It allows one to express moments of the cutoff $$P(\Phi)_ 2$$ fields in terms of multiple local times for the Brownian motion and can be applied to investigate local times and self-crossing properties of Markov processes.
