Quasi-periodic travelling waves for beam equations with damping on 3-dimensional rectangular tori
Quasi-periodic travelling waves for beam equations with damping on 3-dimensional rectangular tori
<p style='text-indent:20px;'>This paper concerns the mathematical analysis of quasi-periodic travelling wave solutions for beam equations with damping on 3-dimensional rectangular tori. Provided that the generators of the rectangular torus satisfy certain relationships, by excluding some values of two model parameters, we establish the existence of small amplitude quasi-periodic travelling wave …
