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…

Continuity properties of Schrödinger semigroups with magnetic fields
Kurt Broderix, Dirk Hundertmark, Hajo Leschke
The objects of the present study are one-parameter semigroups generated by Schrödinger operators with fairly general electromagnetic potentials. More precisely, we allow scalar pot…
