On localized solutions of discrete nonlinear Schrodinger equation. An exact result
P. Pacciani, V. V. Konotop, G. Perla Menzala
Local and global existence of localized solutions of a discrete nonlinear Schrodinger (DNLS) equation, with arbitrary on-site nonlinearity, is proved. In particular, it is shown th…

On global existence of localized solutions of some nonlinear lattices
G. Perla Menzala, V. V. Konotop
We prove global existence and uniqueness of solutions of some important nonlinear lattices which include the Fermi-Pasta-Ulam (FPU) lattice. Our result shows (on a particular examp…
