Rogue wavefunctions due to noisy quantum tunneling potentials
(Işık University Press, 2017-02-02)
In this paper, we study the effects of white-noised potentials on nonlinear quantum tunneling. We use a split-step scheme to numerically solve the nonlinear Schrodinger equation (NLSE) with a tunneling potential. We consider ...
Residual closeness for helm and sunflower graphs
(Işık University Press, 2017-06-06)
Vulnerability is an important concept in network analysis related with the ability of the network to avoid intentional attacks or disruption when a failure is produced in some of its components. Often enough, the network ...
Streamline upwind/Petrov Galerkin solution of optimal control problems governed by time dependent diffusion-convection-reaction equations
(Işık University Press, 2017)
The streamline upwind/Petrov Galerkin (SUPG) finite element method is studied for distributed optimal control problems governed by unsteady diffusion-convectionreaction equations with control constraints. We derive stability ...
B-Spline collocation method for numerical solution of nonlinear kawahara and modified kawahara equations
(Işık University Press, 2017)
In this paper, a collocation method is applied for solving the Kawahara and modified Kawahara equations. For the spatial discretization, we use the sextic B-spline collocation (SBSC) method on uniform meshes, finite ...
Existence and multiple positive solutions to systems of differential equations of fractional order
(Işık University Press, 2017-03-07)
We show under some conditions the existence and multiplicity of positive solutions for a system of differential equations of fractional order, subject to two-point boundary conditions by applying the fixed point index ...
Generalized ? ? ?-geraghty multivalued mappings on b-metric spaces endowed with a graph
(Işık University Press, 2017-01-12)
In this paper, we provide some conditions for the existence of a coincidence point of single-valued and multivalued mappings involving generalized ? ? ?-Geraghty contractions endowed with a graph. Our main results improve ...
Fixed point theorems for generalized (?, ?)-weak contractions
(Işık University Press, 2017)
In this paper, we prove some fixed point theorems for generalized (?, ?)-weak contractive mappings in a metric space. Our result generalized and extend recent results of Singh et al.[16, Theorem 2.1], Dori´c [7, Theorem ...
On trans-Sasakian manifold equipped with m-projective curvature tensor
(Işık University Press, 2017-05-22)
The work towards of the attending paper is to interpret the trans-Sasakian manifold equipped with m-projective curvature tensor and its various geometric properties. First, we observe that m-projectively flat trans-Sasakian ...
Matrix transform of irregular weyl-heisenberg wave packet frames for L² (R)
(Işık University Press, 2017)
Cordoba and Fefferman [4] introduced wave packet systems by applying certain collections of dilations, modulations and translations to the Gaussian function in the study of some classes of singular integral operators. In ...
Graphs cospectral with multicone graphs KW 5 L(P)
(Işık University Press, 2017)
E. R. van Dam and W. H. Haemers [15] conjectured that almost all graphs are determined by their spectra. Nevertheless, the set of graphs which are known to be determined by their spectra is small. Hence, discovering infinite ...
