On the numerical solution to optimal control problems with non-local conditions
(Işık University Press, 2020)
Optimal control problems involving non-separated multipoint and integral conditions are investigated. For numerical solution to the problem, we propose to use first order optimization methods with application of the formulas ...
Multiple positive solutions for a system of fractional higher-order infinite-point boundary value problems
(Işık University Press, 2020)
In this article, we establish some results on the existence of multiple positive solutions for a system of nonlinear fractional order infinite-point boundary value problems. The main tool is a fixed point theorem of the ...
Linear optimization method on single valued neutrosophic set and its sensitivity analysis
(Işık University Press, 2020)
Recently, decision making problems has prompted extensive awareness, especially multi-attribute decision-making problem in single valued neutrosophic sets. Given the inherent characteristics of this case, a multi-attribute ...
Multiplicity results to a fourth-order boundary value problem for a Sturm-Liouville type equation
(Işık University Press, 2020)
We establish the existence of at least three distinct weak solutions for a fourth-order Sturm-Liouville type problem under appropriate hypotheses. Our main tools are based on variational methods and some critical points ...
Inequalities via strongly (p, h)-harmonic convex functions
(Işık University Press, 2020)
The main aim of this paper is to consider a new class of harmonic convex functions with respect to an arbitrary non-negative function, which is called strongly (p, h)-harmonic convex function. We establish Hermite-Hadamard ...
Fuzzy soft quasi separation axioms
(Işık University Press, 2020)
In this work, we focus on fuzzy soft quasi separation axioms and give some new results about the concept of quasi coincidence with fuzzy soft sets defined in [17]. Further, we give relations between fuzzy soft quasi Tᵢ−(i ...
On fuzzy quotient BCK-algebras
(Işık University Press, 2020)
In this paper, by considering the concept of fuzzy congruence in some algebraic structures, we specially study fuzzy congruence in BCK-algebras. We prove that there is a bijection between the set of fuzzy ideals and the ...
Edge domination in some brick product graphs
(Işık University Press, 2020)
Let G = (V, E) be a simple connected and undirected graph. A set F of edges in G is called an edge dominating set if every edge e in E − F is adjacent to at least one edge in F. The edge domination number γ′ (G) of G is ...
Addition theorem and certain properties of k-bessel function
(Işık University Press, 2020)
Our purpose in this paper is to study certain basic properties of k-Bessel function, introduced by Gehlot [Nonl. Anal. Diff. Eq., 2(2)(2014), 61-67]. In this regard, we obtain addition theorem, expansions formula, integral ...
A fixed point problem via simulation functions in incomplete metric spaces with its application
(Işık University Press, 2020)
In this paper, firstly, we review the notion of the SO-complete metric spaces. This notion let us to consider some fixed point theorems for single-valued mappings in incomplete metric spaces. Secondly, as motivated by the ...
