A class of multi - parameter eigenvalue problems for perturbed p-Laplacians
Güngör, Faruk; Hasansoy, Mahir (Elsevier, 2012-05-15)This paper is devoted to multi-parameter eigenvalue problems for one-dimensional perturbed p-Laplacians, modelling travelling waves for a class of nonlinear evolution PDE. Dispersion relations between the eigen-parameters, ... -
Eigenvalue problems for perturbed p-Laplacians
Hasansoy, Mahir (American Institute of Physics, 2010-11)This main subject of this paper is the problem of the existence of eigenvectors and a dispersion analysis of a class of multi parameter eiegenvalue problems for perturbed p-Laplacians. This paper is particularly, devoted ... -
On the travelling waves for the generalized nonlinear schrodinger equation
Hasansoy, Mahir (Hindawi Publishing Corporation, 2011)This paper is devoted to the analysis of the travelling waves for a class of generalized nonlinear Schrodinger equations in a cylindric domain. Searching for travelling waves reduces the problem to the multiparameter ... -
The spectra of two - parameter quadratic operator pencils
Hasansoy, Mahir (Elsevier, 2011-07)This paper is devoted to a variational theory of the eigenvalue spectra of two-parameter, unbounded operator pencils, of the so-called waveguide type, which have important physical applications. It is known that the ... -
A variable coefficient nonlinear Schrödinger equation with a four-dimensional symmetry group and blow-up
Güngör, Faruk; Hasansoy, Mahir; Özemir, Cihangir (Taylor & Francis, 2013-06)A canonical variable coefficient nonlinear Schrödinger equation with a four-dimensional symmetry group containing SL(2, ℝ) group as a subgroup is considered. This typical invariance is then used to transform by a symmetry ... -
A variational approach to the problem of oscillations of an elastic half cylinder
Hasansoy, Mahir (Iranian Mathematical Society, 2012)This paper is devoted to the spectral theory (more precisely, to the variational theory of the spectrum) of guided waves in an elastic half cylinder. We use variational methods to investigate several aspects of propagating ...
