Sharp Gaussian upper bounds for Schrödinger semigroups on the half-line
Paul Holst, Hendrik Vogt
In 1998, V. Liskevich and Y. Semenov showed sharp Gaussian upper bounds for Schrödinger semigroups on with potentials satisfying a global Kato class condition. Using…

Well-posedness and long-term behaviour for a troposphere wave propagation model
Paul Holst, Jens Rademacher
In this paper, we investigate a model recently derived by A. Constantin and R.S. Johnson for nonlinear wave propagation in the troposphere, particularly the 'morning glory' cloud p…
