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 ...
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, 2017-01-25)
The paper presents analytical and semi-numerical 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, 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 α − ψ-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 α − ψ-Geraghty contractions endowed with a graph. Our main results improve ...
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 ...
The perturbation to non-Markovian equation of motion corresponding to coherent and quadrature non-Markovian SSES
(Işık University Press, 2017)
In this paper, we derive the perturbation and post Markovian perturbation to non-Markovian equation of motion(NMEM) that correspond to coherent and quadrature non-Markovian stochastic Schr¨odinger equations (SSE). In that ...
Position vector of a developable h-slant ruled surface
(Işık University Press, 2017)
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 ...
Fixed point theorems for generalized (ψ, ϕ)-weak contractions
(Işık University Press, 2017)
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 ...
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 ...
