Pointwise Approximation Theorems for Combinations of Bernstein Polynomials With Inner Singularities
Wen-Ming Lu, Lin Zhang
We give direct and inverse theorems for the weighted approximation of functions with inner singularities by combinations of Bernstein polynomials.

Pointwise weighted approximation of functions with endpoint singularities by combinations of Bernstein operators
Wen-ming Lu, Lin Zhang
We give direct and inverse theorems for the weighted approximation of functions with endpoint singularities by combinations of Bernstein operators.
Pointwise weighted approximation of functions with inner singularities by combinations of Bernstein operators
Wen-ming Lu, Lin Zhang
We introduce another new type of combinations of Bernstein operators in this paper, which can be used to approximate the functions with inner singularities. The direct and inverse…
Pointwise weighted approximation of functions with inner singularities by Bernstein operators
Wen-ming Lu, Lin Zhang
We consider the pointwise weighted approximation by Bernstein operators with inner singularities. The related weight functions are weights In thi…
Another weighted approximation of functions with singularities by combinations of Bernstein operators
Wen-ming Lu, Lin Zhang
A new type of combinations of Bernstein operators is given in [1]. Here, we introduce another one, which can be used to approximate the functions with singularities. The direct and…
