A Galerkinlike scheme to determine curves of constant breadth in Euclidean 3space
(Işık University Press, 2021)The main focus of this study is to obtain the approximate solutions of a first order linear differential equation system characterizing curves of constant breadth in Euclidean 3space. For this purpose, we outline a ... 
Harmonic reciprocal status index and coindex of graphs
(Işık University Press, 2021)The reciprocal status of a vertex u is defined as the sum of reciprocal of the distances between u and all other vertices of a graph G. In this paper we have defined the harmonic reciprocal status index and coindex of a ... 
Hosoya polynomial of a multibridge graph
(Işık University Press, 2021)Explicit expressions of the Hosoya polynomials of some classes of graphs are known. In this paper we find an explicit expression for the Hosoya polynomial of the multibridge graph. Finally we give some examples of multibridge ... 
Impact of initial time difference on stability criteria of impulsive differential equations
(Işık University Press, 2021)In this paper, an impulsive differential system is investigated for the first time for several stability criteria relative to initial time difference. The investigations are carried out by perturbing Lyapunov functions and ... 
Kgfusion woven in Hilbert spaces
(Işık University Press, 2021)In this note, we study weaving Kgfusion frames in separable Hilbert spaces which motivated by a generalized of fusion frames. We present necessary and sufficient conditions for these woven and also construct them by a ... 
Method based on quasi variable mesh for solution of system of second order boundary value problems with mixed boundary conditions
(Işık University Press, 2021)A new numerical method with third order accuracy is presented for the solution of nonlinear two point boundary value problems(BVPs) with mixed boundary conditions using quasi variable mesh. In case of uniform mesh, method ... 
The method of fundamental solutions for the inverse timedependent perfusion coefficient problem
(Işık University Press, 2021)This paper deals with an inverse problem associated with the bioheat equation in living tissue in the human body. The inverse problem consists of the identification of timedependent perfusion coefficient when the exact ... 
Minimal restrained monophonic sets in graphs
(Işık University Press, 2021)For a connected graph G = (V, E) of order at least two, a restrained monophonic set S of a graph G is a monophonic set such that either S = V or the subgraph induced by V −S has no isolated vertices. The minimum cardinality ... 
m−Polar neutrosophic graphs
(Işık University Press, 2021)The concept of m−Polar antipodal single valued neutrosophic graph (m−PASVNG), eccentric m−PSVNG, self centered m−PSVNG and self median m−PSVNG of the given m−PSVNG are introduced here. We also investigate different types ... 
New intuitionistic fuzzy 2 normed Iconvergent double sequence spaces by bounded linear operator
(Işık University Press, 2021)Saadati and Park [Saadati. R, and Park J. H., Chaos, Solitons Fractals 2006] [14] introduced the notion of intuitionistic fuzzy normed space. Motivated by this, we introduce some intuitionistic fuzzy 2normed Iconvergent ... 
A novel finite difference scheme for time fractional diffusionwave equation with singular kernel
(Işık University Press, 2021)In this paper, we suggest a novel numerical approximation of the CaputoFabrizio fractional derivative of order α (1 < α < 2). Our novel discretization is found by using discret fractional derivative at t = tk with new ...

Radial basis function generated finite difference method for the solution of sinhGordon equation
(Işık University Press, 2021)Accuracy of radial basis functions (RBFs) is increased as the shape parameter decreases and produces an illconditioned system. To overcome such difficulty, the global stable computation with Gaussian radial basis functionQR ...
