An improved upper bound for the Froude number of irrotational solitary water waves

Evgeniy Lokharu, Jörg Weber

A classical and central problem in the theory of water waves is to classify parameter regimes for which non-trivial solitary waves exist. In the two-dimensional, irrotational, pure…

Rigidity of symmetric doubly-periodic water waves near shear flows

Douglas Svensson Seth, Kristoffer Varholm, Erik Wahlén +1

We prove that symmetric, doubly periodic, capillary-gravity water waves in finite depth bifurcating from non-uniform non-stagnant shear flows are necessarily two-dimensional to lea…

Axisymmetric capillary water waves with vorticity and swirl connecting to static unduloid configurations

Anna-Mariya Otsetova, Erik Wahlén, Jörg Weber

We study steady axisymmetric water waves with general vorticity and swirl, subject to the influence of surface tension. Explicit solutions to such a water wave problem are static c…

Large-amplitude steady gravity water waves with general vorticity and critical layers

Erik Wahlén, Jörg Weber

We consider two-dimensional steady periodic gravity waves on water of finite depth with a prescribed but arbitrary vorticity distribution. The water surface is allowed to be overha…

Controlling a Vlasov-Poisson plasma by a Particle-In-Cell method based on a Monte Carlo framework

Jan Bartsch, Patrik Knopf, Stefania Scheurer +1

The Vlasov-Poisson system describes the time evolution of a plasma in the so-called collisionless regime. The investigation of a high-temperature plasma that is influenced by an ex…
