Continuous integral kernels for unbounded Schroedinger semigroups and their spectral projections

Kurt Broderix, Hajo Leschke, Peter Müller

By suitably extending a Feynman-Kac formula of Simon [Canadian Math. Soc. Conf. Proc, 28 (2000), 317-321], we study one-parameter semigroups generated by (the negative of) rather g…
