A splitting scheme for the wave maps equation at low regularity
Katie Marsden, Frédéric Rousset, Katharina Schratz
We prove convergence of a filtered Lie splitting scheme for the wave maps equation with low regularity initial data in dimension 3. The convergence analysis is performed in discret…

The Hamiltonian formulation of continuum Calogero-Moser models
Rowan Killip, Katie Marsden, Monica ViÅan
Recent well-posedness results have identified the Hardy space as the natural phase space for continuum Calogero-Moser models, both focusing and defocusing, on the line and…
