Nonlinear lattices from the physics of ecosystems: The Lefever-Lejeune nonlinear lattice in ${\mathbb{Z}}^2$

Nikos I. Karachalios, Antonis Krypotos, Paris Kyriazopoulos

We argue that the spatial discretization of the strongly nonlinear Lefever-Lejeune partial differential equation defines a nonlinear lattice that is physically relevant in the cont…
