We consider a model created by diffraction in periodic media.The study of the traveling wave solutions for this model derives a planar dynamical systems wit
It is known that the spectral type of the almost Mathieu operator depends in a fundamental way on both the strength of the coupling constant and the arithme
In this talk,we deal with Aronszajn-type topological structure of the solution sets for Cauchy problems of nonlinear evolution inclusions.The underlying fea
