BSpline collocation method for numerical solution of nonlinear kawahara and modified kawahara equations
(Işık University Press, 20161107)In this paper, a collocation method is applied for solving the Kawahara and modified Kawahara equations. For the spatial discretization, we use the sextic Bspline collocation (SBSC) method on uniform meshes, finite ... 
Dirichlet series and approximate analytical method for the solution of mhd boundary layer flow of casson fluid over a stretching/shrinking sheet
(Işık University Press, 20170125)The paper presents analytical and seminumerical solution for magnetohydrodynamic (MHD) boundary layer flow of Casson fluid over a exponentially permeable shrinking sheet. The governing partial differential equations of ... 
Existence and multiple positive solutions to systems of differential equations of fractional order
(Işık University Press, 20170307)We show under some conditions the existence and multiplicity of positive solutions for a system of differential equations of fractional order, subject to twopoint boundary conditions by applying the fixed point index ... 
Fixed point theorems for generalized (ψ, ϕ)weak contractions
(Işık University Press, 20160920)In this paper, we prove some fixed point theorems for generalized (ψ, ϕ)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 ... 
Generalized weighted Cebysev and Ostrowski type inequalities for double integrals
(Işık University Press, 20161030)In this paper, we firstly establish generalized weighted Montgomery identity for double integrals. Then, some generalized weighted Cebysev and Ostrowski type inequalities for double integrals are given. 
Generalized α − ψgeraghty multivalued mappings on bmetric spaces endowed with a graph
(Işık University Press, 20170112)In this paper, we provide some conditions for the existence of a coincidence point of singlevalued and multivalued mappings involving generalized α − ψGeraghty contractions endowed with a graph. Our main results improve ... 
Graphs cospectral with multicone graphs KW 5 L(P)
(Işık University Press, 20161102)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 ... 
LyapunovSchmidt reduction in the study of periodic travelling wave solutions of nonlinear dispersive long wave equation
(Işık University Press, 20161003)This article studies the bifurcation of periodic travelling wave solutions of nonlinear dispersive long wave equation by using LyapunovSchmidt reduction. We determined the conditions for the existence of regular solutions ... 
Matrix transform of irregular weylheisenberg wave packet frames for L2 (R)
(Işık University Press, 20161012)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 ... 
Nonholonomic frames for finsler space with deformed matsumoto metric
(Işık University Press, 20160927)The purpose of present paper is to find the nonholonomic frames for the deformed Matsumoto type metric which are given in the forms I. (α2/α−β)α =α3/α−β II. (α2/α−β)β =α2β/α−β where α2 = aij (x)yi yj and β = bi(x)yi. The ...

(Işık University Press, 20170522)The work towards of the attending paper is to interpret the transSasakian manifold equipped with mprojective curvature tensor and its various geometric properties. First, we observe that mprojectively flat transSasakian ... 
The perturbation to nonMarkovian equation of motion corresponding to coherent and quadrature nonMarkovian SSES
(Işık University Press, 20160920)In this paper, we derive the perturbation and post Markovian perturbation to nonMarkovian equation of motion(NMEM) that correspond to coherent and quadrature nonMarkovian stochastic Schr¨odinger equations (SSE). In that ... 
Position vector of a developable hslant ruled surface
(Işık University Press, 20160920)In physics and geometry, the determination of position vector of a moving point is an important problem, since the trajectory of that point is a curve or a surface which are important in physics, geometry, and applied ... 
Residual closeness for helm and sunflower graphs
(Işık University Press, 20170606)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 ... 
Rogue wavefunctions due to noisy quantum tunneling potentials
(Işık University Press, 20170202)In this paper, we study the effects of whitenoised potentials on nonlinear quantum tunneling. We use a splitstep scheme to numerically solve the nonlinear Schrodinger equation (NLSE) with a tunneling potential. We consider ... 
Some results on total chromatic number of a graph
(Işık University Press, 20170824)A total coloring of a graph is a proper coloring in which no two adjacent or incident graph elements receive the same color. The total chromatic number of a graph is the smallest positive integer for which the graph admits ...
