Bleimann, Butzer, and Hahn Operators Based on the q-Integers
(Hindawi Publishing Corporation, 2007)We give a new generalization of Bleimann, Butzer, and Hahn operators, which includes q-integers. We investigate uniform approximation of these new operators on some subspace of bounded and continuous functions. In Section ... -
Fixed points of weakly compatible maps satisfying a general contractive condition of integral type
(Springer, 2007)We prove a fixed point theorem for weakly compatible maps satisfying a general contractive condition of integral type. Copyright (C) 2007. -
A common fixed point theorem for weakly compatible mappings in symmetric spaces satisfying an implicit relation
(Soc Matematica Mexicana, 2007)In this paper, we prove a common fixed point theorem for weakly compatible mappings in symmetric spaces satisfying an implicit relation and a fixed point thorems under strict contractive conditions, J. Math. Anal. Appl. ... -
The estimates of approximation by using a new type of weighted modulus of continuity
(Pergamon-Elsevier Science Ltd, 2007)In this paper, we introduce a new type modulus of continuity for function f belonging to a particular weighted subspace of C (0, infinity) and show that it has some properties of ordinary modulus of continuity. We obtain ... -
Approximation of functions of two variables by certain linear positive operators
(Springer India, 2007)We introduce certain linear positive operators and study some approximation properties of these operators in the space of functions, continuous on a compact set, of two variables. We also find the order of this approximation ... -
Position vectors of a spacelike W-curve in minkowski space E1 3
(Korean Mathematical Soc, 2007)In this paper, we study the position vectors of a spacelike W-curve (or a helix), i.e., curve with constant curvatures, with spacelike, timelike and null principal normal in the Minkowski 3-space E-1(3). We give some ... -
On behaviour of the Riesz and generalized Riesz potentials as order tends to zero
(Element, 2007)In this paper, we present the Riesz potentials I-alpha and the generalized Riesz potentials I-v(alpha) as the families of positive linear operators, depending on parameter alpha > 0. We investigate their pointwise convergence ... -
Tensor product surfaces of a Lorentzian space curve and a Euclidean plane curve
(Academic Publication Council, 2007)In this paper, we classify all minimal, totally real and complex tensor product surfaces of a Lorentzian space curve and a Euclidean plane curve. -
On the generalized Picard and Gauss Weierstrass singular integrals
(Eudoxus Press, Llc, 2006)In this paper, we give the generalizations of the Picard and the Gauss Weierstrass singular integral operators which are based on the q-numbers and depend on q-generalization of the Euler gamma integral. Later on, some ... -
An alternative algorithm for a sliding window ULV decomposition
(Springer Wien, 2006)The ULV decomposition (ULVD) is an important member of a class of rank-revealing two-sided orthogonal decompositions used to approximate the singular value decomposition (SVD). The ULVD can be modified much faster than the ... -
The q-derivative and applications to q-Szasz Mirakyan operators
(Springer, 2006)By using the properties of the q-derivative, we show that q-Szasz Mirakyan operators are convex, if the function involved is convex, generalizing well-known results for q = 1. We also show that q-derivatives of these ... -
On approximation properties of a family of linear operators at critical value of parameter
(Academic Press Inc Elsevier Science, 2006)We introduce the family of linear operators [GRAPHICS] associated to a certain "admissible bunch" of operators S-t, t > 0, acting on L-p (R-n, dm, and investigate the approximation properties of this family as alpha -> ... -
Subspaces of A-statistically convergent sequences
(Akademiai Kiado, 2003)Let A be a nonnegative regular summability method. In this paper we deal with various subspaces of A-statistically convergent sequences by using the rate of convergence concept. We show, under certain conditions, that these ... -
Fixed point theorems on uniform spaces
(Indian Nat Sci Acad, 2003)Two general fixed point theorems for F: (X, U) --> (2(X), U*) are proved. Examples are given to illustrate the generality of the theorems. -
Fixed point of multivalued mapping in uniform spaces
(Indian Academy Sciences, 2003)In this paper we prove some new fixed point theorems for multivalued mappings on orbitally complete uniform spaces. -
On accelerated iterative methods for the solution of systems of linear equations
(Taylor & Francis Ltd, 2002)In literature, it has been reported that the convergence of some preconditioned stationary iterative methods using certain type upper triangular matrices as preconditioners are faster than the basic iterative methods. In ... -
A certain subclass of analytic functions involving operators of fractional calculus
(Pergamon-Elsevier Science Ltd, 1998)Making use of certain operators of fractional calculus, we introduce a new class T-mu(n,lambda,alpha) of functions which are analytic and univalent in the open unit disk U and obtain a necessary and sufficient condition ... -
Some families of multivalently analytic functions with negative coefficients
(Academic Press Inc Jnl-Comp Subscriptions, 1997)The authors introduce and study three novel subclasses of analytic and p-valent functions with negative coefficients. In addition to finding a necessary and sufficient condition for a function to belong to each of these ... -
