On the Travelling Waves for the Generalized Nonlinear Schrödinger Equation

open access: yesAbstract and Applied Analysis, 2011
This paper is devoted to the analysis of the travelling waves for a class of generalized nonlinear Schrödinger equations in a cylindric domain. Searching for travelling waves reduces the problem to the multiparameter eigenvalue problems for a class of ...

Simple eigenvalues and bifurcation for a multiparameter problem [PDF]

open access: yesProceedings of the Edinburgh Mathematical Society, 1988
We are concerned with the problem of bifurcation of solutions of a non-linear multiparameter problem at a simple eigenvalue of the linearised problem.Let X and Y be real Banach spaces, and let A, Bi, i = 1, …, n∈B(X, Y). Let : Rn × X → Y be a non-linear mapping. We consider the equationwhereand λ=(λ1, λ2,…,λn) ∈ Rn is an n-tuple of spectral parameters.

Perturbation theory of multiparameter eigenvalue problems

open access: yesJournal of Mathematical Analysis and Applications, 1988
Let \(T_ r\) and \(V_{rs}\) be linear selfadjoint operators in Hilbert spaces \({\mathfrak H}_ r\). Let \(\lambda_ s\) be complex parameters. Then it is considered the multiparameter system \[ (T_ r+\sum^{k}_{s=1}\lambda_ sV_{rs})u_ r=0,\quad r=1,...,k. \] The main objective is to study the influence of perturbations for the operators \(T_ r\).

Abstract oscillation theorems for multiparameter eigenvalue problems

open access: yesJournal of Differential Equations, 1983
AbstractWe prove abstract analogous of Klein's oscillation theorem by demonstrating the existence (and in some cases uniqueness) of eigenpairs with a given index for the multiparameter problem Tmxm = ∑n = 1k λnVmnxm, 0 ≠ xm ϵ Hm, m = 1 … k. (∗) Here Tm and Vmn are self-adjoint operators on Hilbert spaces Hm. The index is based on the number of negative

Dual variational approaches to multiparameter eigenvalue problems

open access: yesJournal of Mathematical Analysis and Applications, 1983
AbstractWe study the abstract multiparameter problem Tmxm = ∑kn=1 λn Vmnxm, 0 ≠ xm ϵ Hm, m = 1,…, k, for selfadjoint operators Tm and Vmn on separable Hilbert spaces Hm. We develop dual variational approaches related to the polar duality between certain convex sets. The “primal” approach has been the basis of several investigations, particularly in the
