Lucas polynomial solution for neutral differential equations with proportional delays
(Işık University Press, 2020)
This paper proposes a combined operational matrix approach based on Lucas and Taylor polynomials for the solution of neutral type differential equations with proportional delays. The advantage of the proposed method is the ...
Bishop’s property (β) and weighted conditional type operators in k-quasi class A*n
(Işık University Press, 2020)
An operator T is said to be k-quasi class A*n operator if T*ᵏ (|Tⁿ⁺¹|²/ⁿ⁺¹− |T*|² ) Tᵏ ≥ 0, for some positive integers n and k. In this paper, we prove that the k-quasi class A*n operators have Bishop, s property (β). Then, ...
A pre-subadditive fuzzy measure model and its theoretical interpretation
(Işık University Press, 2020)
In this paper a particular set function which depends on densities of singletons with interdependence coefficients and which provides redundancy among singletons is considered. The Möbius representation of this function ...
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 ...
On the Chebyshev polynomial coefficient problem of bi-Bazilevič functions
(Işık University Press, 2020)
A function said to be bi-Bazilevič in the open unit disk U if both the function and its inverse are Bazilevič there. In this paper, we will study a newly constructed class of bi-Bazilevič functions. Furthermore, we establish ...
Approximation of periodic functions by sub-matrix means of their fourier series
(Işık University Press, 2020)
Some results on approximation of periodic functions are extended in two directions: Improving the degree of approximation of periodic functions by sub-matrix means of its Fourier series and such degree is applicable for a ...
Global attractor of the hyperbolic relaxation of the Swift-Hohenberg equation in Rⁿ
(Işık University Press, 2020)
In this paper, the hyperbolic modification of the Swift-Hohenberg equation in Rⁿ is dealt with. The existence of the global attractor in H² (Rⁿ)×L² (Rⁿ) is proved. Also, the smoothness and the finite dimensionality of the ...
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 ...
ϕ-Best proximity point theorems in metric spaces with applications in partial metric spaces
(Işık University Press, 2020)
In this paper, we introduce the notions of (F, ϕ, θ)-proximal contraction and (F, ϕ, θ)-weak proximal contraction for non-self mappings and utilize the same to prove some existence and uniqueness of ϕ-best proximity point ...
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 ...
