Traveling Waves for the Nonlinear Variational Wave Equation
Katrin Grunert, Audun Reigstad
We study traveling wave solutions of the nonlinear variational wave equation. In particular, we show how to obtain global, bounded, weak traveling wave solutions from local, classi…

A Regularized System for the Nonlinear Variational Wave Equation
Katrin Grunert, Audun Reigstad
We derive a new generalization of the nonlinear variational wave equation. We prove existence of local, smooth solutions for this system. As a limiting case, we recover the nonline…

Competition Models for Plant Stems
Alberto Bressan, Sondre T. Galtung, Audun Reigstad +1
The models introduced in this paper describe a uniform distribution of plant stems competing for sunlight. The shape of each stem, and the density of leaves, are designed in order…
