VORNICESCU, Neculae, APPROXIMATION OF FUNCTIONS OF TWO VARIABLES BY DISCRETE LINEAR POSITIVE OPERATORS

We introduce a class of discrete linear positive operators in the space of real continuous functions of two variables defined on the square [0,1] x [0,1]. These operators are associated to an arbitrary set of nodes

Uniform weighted approximation by positive linear operators

We characterize the functions defined on a weighted space, which are uniformly approximated by a sequence of positive linear operators and we obtain the range of the weights which can be used for uniform approximation. We, also, obtain an estimation of the remainder in terms of the usual modulus of continuity. We give particular results for the Szász-Mirakjan and Baskakov operators. Mathematics...

Approximation of fractional positive stable continuous-time linear systems by fractional positive stable discrete-time systems

In positive systems inputs, state variables and outputs take only non-negative values. Examples of positive systems are industrial processes involving chemical reactors, heat exchangers and distillation columns, storage systems, compartmental systems, or water and atmospheric pollution models. A variety of models having positive linear behavior can be found in engineering, management science, e...

On the Approximation of Trivariate Functions by Means of Some Tensor-product Positive Linear Operators

In this paper we introduce and study a trivariate linear positive operator, depending on some parameters, denoted by L〈α,β,γ〉 m,n,r , useful for the approximation of functions of three real variables continuous on the unit cub C3. The corresponding approximation formula has the degree of exactness (1, 1, 1). For the remainder of this formula we give several representations by using the second-o...
