Exact propagators for soliton potentials

We show that the technique of Darboux transformation operators is very efficient in calculating exact propagators for transformed Hamiltonians. We apply it for getting exact propagators for multisoliton potentials. This permits us to give a closed expression for path integrals involving soliton potentials.
