On the Chebyshev polynomial coefficient problem of bi-Bazilevi? functions
(Işık University Press, 2020)A function said to be bi-Bazilevi? in the open unit disk U if both the function and its inverse are Bazilevi? there. In this paper, we will study a newly constructed class of bi-Bazilevi? functions. Furthermore, we establish ... -
Bishop’s property (?) 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*? (|T??¹|²/??¹? |T*|² ) T? ? 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 (?). Then, ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Linear combinations of q-starlike functions of order alpha
(Işık University Press, 2020)In this paper, we introduced a new concept of bounded radius rotation to define the class of q-starlike functions of order ? using the q-derivative, some geometric properties of linear combination of such functions are studied. -
?-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, ?, ?)-proximal contraction and (F, ?, ?)-weak proximal contraction for non-self mappings and utilize the same to prove some existence and uniqueness of ?-best proximity point ... -
Backscattering from soft-hard triangular cylinder: primary PTD approximation
