Fixed points and its applications in C* algebra valued partial metric space
(Işık University Press, 2021)We familiarise with the concepts of contractiveness and expansiveness in a C* algebra valued partial metric space and create an environment for the existence of fixed point in it. We solve an integral equation and an ... 
The theory of UD derivative and its applications
(Işık University Press, 2021)The sole purpose of this study is to propose a new concept to fractional derivative as UjlayanDixit derivative in the classical sense using limit approach. The parameter α of the derivative is confined within a closed ... 
VL Index and bounds for the tensor products of F−Sum graphs
(Işık University Press, 2021)In QSAR/QSPR study, topological indices are exploited to a presumption of the bioactivity of chemical compounds. Inspired by the work of Zagreb indices, we propound here a new topological index, namely Veerabhadraiah Lokesha ... 
Nonlinear dark solitary SH waves in a heterogeneous layer
(Işık University Press, 2021)In this study, we consider the nonlinear propagation of shear horizontal (SH) waves in a layer of finite thickness. The materials of the layer are assumed to be heterogeneous, isotropic, and generalized neoHookean. We ... 
Algebraic construction of semi bent function via known power function
(Işık University Press, 2021)The study of semi bent functions (2 plateaued Boolean function) has attracted the attention of many researchers due to their cryptographic and combinatorial properties. In this paper, we have given the algebraic construction ... 
Existence of fixed point and best point of proximity for multifunctional non self mappings in a partial metric space
(Işık University Press, 2021)In this paper we give some theorems of existence of best points of proximity for a multifunctional nonselfmapping in a partial metric space and some approximations on the sets of the best points of proximity. Other results ... 
Sălăgeantype analytic functions associated with the Janowski functions and q−difference operator
(Işık University Press, 2021)We introduce three new subclasses of Sălăgeantype analytic functions by using Janowski functions and q−difference operator. We investigate inclusion theorem, sufficient coefficient estimates and distortion bounds for the ... 
On 2absorbing fuzzy ideals of commutative semirings
(Işık University Press, 2021)The purpose of this paper is to introduce and study 2absorbing fuzzy ideals of commutative semirings. Some basic operations on them are defined and some of its characterizations are obtained. 
A numerical treatment of block nuclear magnetic resonance flow equation
(Işık University Press, 2021)The timedependent Bloch nuclear magnetic resonance flow equation in one dimensional space is investigated numerically. To investigate some physiological and biological properties of living tissues NMR plays pivotal role. ... 
Analytical approximate solutions of timefractional integrodifferential equations using a new iterative technique
(Işık University Press, 2021)In this manuscript, a new iterative technique is proposed to obtain the solutions of linear and nonlinear timefractional integrodifferential equations. The suggested algorithm is a modification of the homotopy analysis ... 
Mostar index of bridge graphs
(Işık University Press, 2021)Topological indices are the numerical descriptors of a molecular structure obtained via molecular graph G. Topological indices are used in the structureproperty relationship, structureactivity relations, and nanotechnology. ... 
Certain subclass of Pascutype bistarlike functions in parabolic domain
(Işık University Press, 2021)Estimates on the coefficients a2 and a3 are obtained for normalized analytic function f in the open disk with f and its inverse g = f−1 satisfy the condition that zf0(z) + λz2f00(z)(1 − λ)f(z) + λzf0(z) and zg0(z) + ... 
On subclasses of mfold symmetric biunivalent functions
(Işık University Press, 2021)In this study, we introduce and investigate two new subclasses of the biunivalent functions which both f(z) and f⁻1 (z) are mfold symmetric analytic functions. Among other results, upper bounds for the coefficients am+1 ... 
Practical stability and boundedness criteria of impulsive differential system with initial time difference
(Işık University Press, 2021)In this paper, an impulsive differential system is investigated for the first time for practical stability and boundedness criteria with respect to initial time difference. The investigations are carried out by perturbing ... 
Some results on vertexedge neighborhood prime labeling
(Işık University Press, 2021)Let G be a graph with vertex set V (G) and edge set E(G). For u ∈ V (G), NV (u) = {w ∈ V (G)uw ∈ E(G)} and NE(u) = {e ∈ E(G)e = uv, for some v ∈ V (G)}. A bijective function f : V (G) ∪ E(G) → {1, 2, 3, . . . , V (G) ∪ ...
