| dc.description.abstract | We consider the Fermi-Pasta-Ulam type systems with saturable nonlinearities that
describes an infinite systems of particles on a two dimensional lattice. The main result concerns the
existence of solitary traveling waves solutions with vanishing relative displacement profiles. By
means of critical point theory, we obtain sufficient conditions for the existence of such solutions. | uk_UA |
