k-Type Bi-null Cartan Slant Helices in R-3(6)
(Southeast Asian Mathematical Soc-Seams, 2018)In the present paper, we give the notion of k-type bi-null Cartan slant helices in R-3(6), where k ( )is an element of {1, 2, 3, 4, 5, 6}. We give the necessary and sufficient conditions for bi-null Cartan curves to be ... -
On some Properties of Tribonacci Quaternions
(Ovidius Univ Press, 2018)In this paper, we give some properties of the Tribonacci and Tribonacci-Lucas quaternions and obtain some identities for them. -
Further Generalizations Of Gamma, Beta And Related Functions
(Univ Prishtines, 2018)In this paper, we present further generalizations of gamma and beta functions by adding extra parameters to their integral representations. Then we introduce new generalizations of hypergeometric and confluent hypergeometric ... -
P-Contractive Mappings On Metric Spaces
(Mathematical Research Press-Math Res, 2018)In the present paper, we introduce a new concept of P-contractive mappings on metric spaces. We prove that every ordinary contractive mapping is also P-contractive but the converse may not be true in general. We provide ... -
Coupled fixed point results on metric spaces defined by binary operations
(Vasyl Stefanyk Precarpathian Natl Univ, 2018)In parallel with the various generalizations of the Banach fixed point theorem in metric spaces, this theory is also transported to some different types of spaces including ultra metric spaces, fuzzy metric spaces, uniform ... -
On Approximation Properties of Baskakov-Schurer-Szasz Operators Preserving Exponential Functions
(Univ Nis, Fac Sci Math, 2018)The goal of this paper is to construct a general class of operators which has known BaskakovSchurer-Szasz that preserving constant and e(2ax), a > 0 functions. Also, we demonstrate the fact that for these operators, moments ... -
A new construction of Szasz-Mirakyan operators
(Springer, 2018)The paper aims to study a generalization of Szasz-Mirakyan-type operators such that their construction depends on a function rho by using two sequences of functions. To show how the function rho play a crucial role in the ... -
A note on Szasz-Mirakyan-Kantorovich type operators preserving e(-x)
(Springer, 2018)In the present article, we study modified form of Szasz-Mirakyan-Kantorovich operators, which reproduce constant and functions. We discuss a uniform convergence result along with a quantitative estimate for the modified operators. -
On Fibonomial Sums Identities With Special Sign Functions: Analytically Q-Calculus Approach
(Walter De Gruyter Gmbh, 2018)Recently Marques and Trojovsky [On some new identities for the Fibonomial coefficients, Math. Slovaca 64 (2014), 809-818] presented interesting two sum identities including the Fibonomial coefficients and Fibonacci numbers. ... -
Weak-type Estimates in Morrey Spaces for Maximal Commutator and Commutator of Maximal Function
(Tokyo Journal Mathematics Editorial Office Acad Center, 2018)In this paper it is shown that the Hardy-Littlewood maximal operator M is not bounded on Zygmund-Money space M-L(log L),M-lambda,M- O < lambda < n, but M is still bounded on M-L(logL),M-lambda for radially decreasing ... -
