Strong asymptotic stability for a coupled system of degenerate wave equations with only one fractional feedback
(Işık University Press, 2023-10)We prove the well-posedness and study the strong asymptotic stability of a coupled system of degenerate wave equations with a fractional feedback acting on one end only. -
Modeling disease transmission dynamics with random data and heavy tailed random effects: the Zika case
(Işık University Press, 2023-10)In this study, we investigate a compartmental model of Zika Virus transmission under random effects. Random effects enable the analysis of random numerical characteristics of transmission, which cannot be modeled through ... -
Stabilization of hyperbolic FitzHugh-Nagumo equations with one interior feedback controller
(Işık University Press, 2023-10)We show that the hyperbolic modification of FitzHugh-Nagumo system defined in a bounded domain G ? R? is global exponetally stablizable by a feedback controller action in an open subdomian ? ? G such that G \ ? is sufficiently ... -
Standard single valued neutrosophic metric spaces with application
(Işık University Press, 2023-07)In recent years, J. R. Kider and Z.A. Hussain have introduced the notion of standard fuzzy metric space and some basic properties were proved. In this paper, we generalize this notion to the setting of single valued ... -
Minimum generating sets for complete graphs
(Işık University Press, 2023-07)Let G be a graph with edges labeled by ideals of a commutative ring R with identity. Such a graph is called an edge-labeled graph over R. A generalized spline is a vertex labeling so that the difference between the labels ... -
Extinction of cholera using deterministic and stochastic models incorporating vigilant human compartment
(Işık University Press, 2023-07)We study the effect of vaccination, sanitation and public health sensitization as prevention and control measures of cholera in deterministic and stochastic frameworks. To achieve this, a deterministic mathematical model ... -
Coincidence point results for hybrid pair of mappings on a dislocated metric space endowed with an arbitrary binary relation
(Işık University Press, 2023-07)We introduce the notion of generalized S-contraction of Nadler type and prove some new coincidence point results for hybrid pair of mappings in 0-complete dislocated metric spaces endowed with an arbitrary binary relation. ... -
On the solutions of some recent open problems in metric fixed point theory
(Işık University Press, 2023-07)In this paper, our aim is to provide new solutions to some open problems given in [18] and [27] about the discontinuity at fixed point and related results. For this purpose, we prove new theorems and corollaries using ... -
Grundy coloring of middle graph of wheel graph families
(Işık University Press, 2023-07)A Grundy k-coloring of a graph G is a proper k-coloring of vertices in G using colors {1, 2, · · · , k} such that for any two colors i and j, i < j, any vertex colored j is adjacent to some vertex colored i. The First-Fit ... -
Some algebraic structure of spherical neutrosophic matrices
(Işık University Press, 2023-07)Some_algebraic_structure_of_spherical_neutrosophic_matrices In this paper, we introduce spherical neutrosophic matrices (SNMs) as generalization of intuitionistic fuzzy matrices, Pythagorean fuzzy matrices, picture fuzzy ... -
Harmonic multivalent functions associated with a (p,q)-analogue of Ruscheweyh operator
(Işık University Press, 2023-07)The aim of this paper is to introduce and investigate a new class of harmonic multivalent functions defined by (p,q)-analogue of Ruscheweyh operator for multivalent functions. For this new class, we obtain a (p,q)-coefficient ... -

(Işık University Press, 2023-07)Based on the basic hypergeometric series r?s, we construct a new generalized q-operator r?s (a1, . . . , ar b1, . . . , bs ; q, ?c?) and obtain some of its identities. Using these identities, we generalize several well-known ... -
Pair difference cordial labeling of some union of graphs
(Işık University Press, 2023-07)Let G = (V, E) be a (p, q) graph. Define ? = {p/2 if p is even p?1/2 if p is odd and L = {±1, ±2, ±3, · · · , ±?} called the set of labels. Consider a mapping f : V ? L by assigning different labels in L to the different ... -
