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 ...
Some fixed point results in the generalized convex metric spaces
(Işık University Press, 2020)
In this study, we introduce a new three step iteration process and show that the iteration process converges to the unique fixed point by two theorems under different conditions of contractive mappings on the generalized ...
Wavelet packets in weighted Sobolev space
(Işık University Press, 2020)
We perform some splitting tricks over wavelets to construct basic wavelet packets in weighted Sobolev space. MRA based wavelet packet functions and their orthogonality at different levels in weighted Sobolev space are ...
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 T??(i ...
Fixed point results from soft metric spaces and soft quasi metric spaces to soft G-metric spaces
(Işık University Press, 2020)
In this paper, soft quasi-metric spaces by means of soft elements are described. Also the presentation of soft G-metric spaces and the existing fixed point results of contractive mappings defined on this kind of spaces are ...
Further results of neutrosophic subalgebras in BCK/BCI-algebras based on neutrosophic points
(Işık University Press, 2020)
In this paper, we investigate several properties of (?, ? ?q(kT ,kI ,kF ))-neutrosophic subalgebra, (?, q(kT ,kI ,kF ))-neutrosophic subalgebra, (q(kT ,kI ,kF ), ? ?q(kT ,kI ,kF ))-neutrosophic subalgebra, and (q(kT ,kI ...
Comparison of integro quadratic and quartic spline interpolation
(Işık University Press, 2020)
In this paper quadratic and quartic B-splines were used for reconstruction of an approximating function, where the integral values of successive subintervals were used instead of function values at the knots. After introducing ...
Backscattering from soft-hard triangular cylinder: primary PTD approximation
(Işık University Press, 2020)
High-frequency diffraction from isosceles triangular cylinders with two faces soft and one face hard is investigated for backscattering case and novel first-order physical theory of diffraction asymptotics are derived. ...
A note on certain topological indices of the derived graphs of subdivision graphs
(Işık University Press, 2020)
In this note, we correct some errors in S. M. Hosamani et al. [TWMS J. App. Eng. Math., 6(2), (2016) pp. 324–332]. The derived graph [G]† of a graph G is the graph having the same vertex set as G, with two vertices of ...
