Almost periodic positive solutions for a delayed nonlinear density dependent mortality Nicholson’s blowflies model on time scales
(Işık University Press, 2022)In this paper we discuss a nonlinear density dependent mortality Nicholson’s blowflies equation with multiple pairs of time varying delays. By contraction mapping theorem, we derived the necessary conditions for the existence ... 
Bipolar intuitionistic fuzzy CK compact spaces
(Işık University Press, 2022)The objective of this article is to initiate the innovative views on bipolar intuitionistic fuzzy topological space, bipolar intuitionistic fuzzy C compact and its preimage, orbit and image followed by some of its special ... 
Boundary value problem solving for semilinear fractional differential equations with nonlocal and integral boundary conditions
(Işık University Press, 2022)In this paper, we will study a boundary value problem for semilinear fractional differential equations of order q ∈ (1, 2] with nonlocal and integral boundary conditions. Some existence and uniqueness results with illustrative ... 
Certain generating functions involving the incomplete Ifunctions
(Işık University Press, 2022)In this paper, we have derived a set of generating functions for incomplete Ifunctions. Bilateral along with linear generating relations are derived for incomplete Ifunctions. The results obtained are of a general nature, ... 
A certain subclass of uniformly convex functions with negative coefficients defined by lambda operator
(Işık University Press, 2022)In this paper, we introduce a new subclass of uniformly convex functions with negative coefficients defined by lambda operator. We obtain the coefficient bounds, growth distortion properties, extreme points and radii of ... 
Changing and unchanging on Tadpole domination number in G − e, G + e graphs
(Işık University Press, 2022)In this paper, the effect of “Tadpole domination” change is examined, which is one of the domination types, when a graph is modified, by deleting or adding an edge in G. This edge deletion may represent a cut in a network. ... 
Convolution conditions for qconvexity, qstarlikeness and qspirallikeness
(Işık University Press, 2022)In the present investigation, the authors derive necessary and sufficient conditions for qstarlike, qconvex functions of order β and qspirallike, convex qspirallike functions using convolution 
‘Del’ relation and parallelism in fuzzy lattices
(Işık University Press, 2022)The notions of ‘del’ relation, a neutral element and parallelism from lattice theory are introduced in a fuzzy lattice and their properties are obtained. 
Determination of a nonlinear source term in a reactiondiffusion equation by using finite element method and radial basis functions method
(Işık University Press, 2022)In this paper, two numerical methods are presented to solve a nonlinear inverse parabolic problem of determining the unknown reaction term in the scalar reactiondiffusion equation. In the first method, the finite element ... 
Effects of heat source/sink on DarcianBenardMagnetoMarangoni convective instability in a composite layer subjected to nonuniform temperature gradients
(Işık University Press, 2022)The problem of BènardMagnetoMarangoni convection in a composite layer which is infinite along x and y directions is considered for the Darcian case in the presence of constant heat source/sink in both the layers. This ... 
Fermatean fuzzy matrices
(Işık University Press, 2022)In this paper, we introduce the concept of Fermatean fuzzy matrices, which are direct extensions of an intuitionistic fuzzy matrices. Then we define some algebraic operations, such as maxmin, minmax, complement, algebraic ... 
Fixed point theorems of fuzzy partial metric spaces
(Işık University Press, 2022)Fuzzy metric space has been defined using fuzzy numbers by many researchers. Recently Xia and Guo [20] have introduced fuzzy metric space using fuzzy scalars which is similar to the classical metric space. In this work we ... 
Generalized cone b−random metric space with some random fixed point theorems
(Işık University Press, 2022)In this paper, we introduce generalized cone b−random metric space and prove some random fixed point theorems for mappings satisfying various contractive type conditions. Also some stochastic fixed point theorems for ... 
Introduction to total dominator edge chromatic number
(Işık University Press, 2022)We introduce the total dominator edge chromatic number of a graph G. A total dominator edge coloring (briefly TDEcoloring) of G is a proper edge coloring of G in which each edge of the graph is adjacent to every edge of ... 
Inverse problem for Albertson irregularity index
(Işık University Press, 2022)Graph indices have attracted great interest as they give us numerical clues for several properties of molecules. Some indices give valuable information on the molecules under consideration using mathematical calculations ... 
Location of burst and repeated burst error in single and adjacent subblocks
(Işık University Press, 2022)The paper gives necessary and sufficient conditions for the existence of linear codes capable of identifying burst/repeated burst errors whether it is confined to one subblock or spread over two adjacent subblocks. ... 
A mean ergodic theorem via weak statistical convergence
