Bivariate Extension of Linear Positive Operators

2016
The goal of this chapter is to present a survey of the literature on approximation of functions of two variables by linear positive operators. We study the approximation properties of these operators in the space of functions of two variables, continuous on a compact set. We also discuss the convergence of the operators in a weighted space of functions

On the Durrmeyer-type operators for bivariate functions

Approximation Theory and its Applications, 1994
The author considers Boolean sums \(\widetilde L_{m, n}f\) of parametric extensions of certain Durrmeyer-type operators \(\widetilde L_m\) and \(\widetilde L_n\) for measurable functions \(f\) of two real variables. The weighted mixed modulus of continuity of \(\widetilde L_{m, n}f\) is estimated and the degree of approximation of \(f\) by \(\widetilde

On the characterization of a class of binary operations on bivariate distribution functions

Publicationes Mathematicae Debrecen, 2006
Summary: We characterize the class of binary operations on bivariate distribution functions that are induced pointwise by a two-place real function (e.g. mixtures) and, in particular, we study these operations on the class of distribution functions whose one-dimensional margins are uniform (i.e. copula).

The bivariate Shepard operator of Bernoulli type

Calcolo, 2007
The author studies the interpolation of very large scattered data sets. She introduces a combined operator of Bernoulli type, using the classical Shepard operator and then a modified Shepard method. They preserve the advantages and improve the reproduction qualities, have better accuracy and better computational efficiency.

On nonlinear bivariate singular integral operators

Mathematical Methods in the Applied Sciences, 2018
In this paper, we give some pointwise convergence and Fatou type convergence theorems for a family of nonlinear bivariate singular integral operators in the following form: urn:x-wiley:mma:media:mma5425:mma5425-math-0006 where m1,m2  ≥  1 are fixed natural numbers, and ω  ∈  Ω, Ω denotes a nonempty set of indices endowed with a topology.

The Combined Shepard-Lidstone Bivariate Operator

2005
We extend the Shepard operator by combining it with the Lidstone bivariate operator. We study this combined operator and give some error bounds.

Bivariate copula-based aggregation operators

2007
This paper presents the role of copulafunc- tions in the theory of aggregation operators. In this context we are focusing our attention abouts everal properties of aggregation functions,like supermodularity andSchur- concavity, studying also a decompositionof supermodular binary aggregation operators and copulae.
