About a general property for a class of linear positive operators and applications

Journal of Numerical Analysis and Approximation Theory, 2005
In this paper we demonstrate a general property for a class of linear positive operators. By particularization, we obtain the convergence and the evaluation for the rate of convergence in term of the first modulus of smoothness for the Bernstein ...

On unitarily invariant norms of matrix-valued linear positive operators

Journal of Inequalities and Applications, 2002
In this paper we prove several inequalities concerning invariant norms of matrices belonging to the range of some matrix-valued Linear Positive Operator (LPO).

Approximation of bounded functions by positive linear operators

Modern Mathematical Methods
A general family of positive linear operators associated with a power expansion is studied. An upper estimate of the rate of convergence is obtained for bounded continuous functions in \([0,\infty)\) that has limit when \(x\to \infty\).

Linear and non-linear price decentralization [PDF]

Compendious and thorough solutions to the existence of a linear price equilibrium problem, the second welfare theorem, and the limit theorem on the core are provided for exchange economies whose consomption sets are the positive cone of arbitrary ordered
