K-g-fusion woven in Hilbert spaces
(Işık University Press, 2021)In this note, we study weaving K-g-fusion 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 ... -
On fuzzy topologies generated by fuzzy relations
(Işık University Press, 2021)In this paper, we have introduced a fuzzy topology generated by a fuzzy relation as a generalization of the corresponding concept given by Smithson and obtained sufficient conditions under which this fuzzy topology becomes ... -
Cm-supermagic labeling of friendship graphs
(Işık University Press, 2021)The friendship graph F?n is obtained by joining n copies of the cycle graph Cm with a common vertex. In this work, we investigate the Cm-supermagic labeling of friendship graphs. -
Radial basis function generated finite difference method for the solution of sinh-Gordon equation
(Işık University Press, 2021)Accuracy of radial basis functions (RBFs) is increased as the shape parameter decreases and produces an ill-conditioned system. To overcome such difficulty, the global stable computation with Gaussian radial basis function-QR ... -
New intuitionistic fuzzy 2- normed I-convergent 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 2-normed I-convergent ... -
Controlled multipliers with two operators in Hilbert C*-modules
(Işık University Press, 2021)Improving and extending the notion of controlled frames, in this paper, we introduce controlled frames with two operators for Hilbert C*-modules. This generalize controlled frames in Hilbert and Hilbert C*-module. We show, ... -
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 ... -
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 ... -
Fixed points in φ-ordered partial quasi-metric space
(Işık University Press, 2021)We obtain fixed points for an order preserving mapping in a preordered left p-complete partial quasi-metric space using a preorder induced by an appropriate function. In particular, we do not make use of any contraction condition. -
Fuzzy congruence on M??groups
(Işık University Press, 2021)In this paper, we consider an algebriac structure M?? group, which is a generalization of both the concepts module over a nearring and a gamma nearring, introduced by Satyanarayana [12]. In this paper, we define a fuzzy ... -
Certain types of graphs in interval-valued intuitionistic fuzzy setting
(Işık University Press, 2021)Interval-valued intuitionistic fuzzy graph (IVIFG) as a generalization of intuitionistic fuzzy graph (IFG) increases its elasticity drastically. In this paper, some important types of IVIFGs such as regular, irregular, ... -
