Existence of heteroclinic traveling waves in a system of oscillators on a two-dimensional lattice
(2016)By using the critical points method and the concentration-compactness principle, the problem of existence of heteroclinic travelling waves for a system of linearly coupled nonlinear oscillators in a two-dimensional lattice ... -
The existence of heteroclinic traveling waves in the discrete sine-Gordon equation with nonlinear interaction on a 2D-lattice
(2018)The article deals with the discrete sine-Gordon equation that describes an infinite system of nonlinearly coupled nonlinear oscillators on a 2D-lattice with the external potential V (r) = K(1-cos r). The main result concerns ...
