General analytic characterization of gaugeability for Feynman-Kac functionals (Q681617)

In this paper, the authors give a general analytic characterization of the gaugeability of generalized Feynman-Kac functionals of symmetric Hunt processes involving continuous additive functionals of zero energy. The main results of this paper generalize previous known results on the analytic characterization of the gaugeability of generalized Feynman-Kac functionals of symmtric Hunt processes satisfying an irreducility condition and an absolute continuity condition.
