Homoclinic solutions of discrete nonlinear Schrodinger equations with partially sublinear nonlinearities

Homoclinic solutions of discrete nonlinear Schrodinger equations with partially sublinear nonlinearities

We consider a class of discrete nonlinear Schrodinger (DNLS) equations in m dimensional lattices with partially sublinear nonlinearity f. Combining variational methods and a priori estimate, we give a general sufficient condition on f for type (A), that is, a sequence of nontrivial homoclinic...
