Positive linear operators with equidistant nodes [PDF]
, 1996 In the present paper, the approximation power of positive linear operators with equidistant nodes is investigated. New pointwise estimates are given in terms of first and second order moduli of continuity, showing that for positive operators having ...

A Theorem of Rolewicz's Type for Measurable Evolution Families in Banach Spaces [PDF]
, 2001 Let $varphi$ be a positive and non-decreasing function defined on the real half-line and ${mathcal U}$ be a strongly measurable, exponentially bounded evolution family of bounded linear operators acting on a Banach space and satisfing a certain ...

Bounded linear operators that preserve the weak supermajorization on $\ell^1(I)^+$ [PDF]
, 2018 Linear preservers of weak supermajorization which is defined on positive functions contained in the discrete Lebesgue space $\ell^1(I)$ are characterized. Two different classes of operators that preserve the weak supermajorization are formed. It is shown

Optimum non linear binary image restoration through linear grey-scale operations [PDF]
, 2003 Non-linear image processing operators give excellent results in a number of image processing tasks such as restoration and object recognition. However they are frequently excluded from use in solutions because the system designer does not wish to ...

On the degree of approximation by positive linear operators using the b-summability method [PDF]
, 1991 The aim of this paper is to sharpen the results of censor [3] and Mahapatra [7] given on the degree approximation by positive linear ...

Convolution operators and the discrete Laplacian [PDF]
, 2009 PhDIn this thesis, we obtain new results for convolution operators on homogeneous spaces and give applications to the Laplacian on a homogeneous graph. Some of these results have been published in joint papers [13, 14] with my supervisor.

Microlocal Analysis of Some Isospectral Deformations [PDF]
, 1994 We study the microlocal structure of the examples of isospectral deformations of Riemannian manifolds given by D. DeTurck and C. Gordon in [DeT-G1]. The Schwartz kernel of the intertwining operators considered by them may be written as an oscillatory ...

Convergence Theorems for Derivatives of a New Baskakov -Type Operators
Wasit Journal for Pure SciencesThe motive of this paper is to introduce and investigate the derivatives of some Baskakov operators. Firstly, we treated with the convergence theorems on some certain type of Baskakov operators and then we found the derivative of these operators.
