Bernstein operators for exponential polynomials

J. M. Aldaz, O. Kounchev, H. Render

Let $L$ be a linear differential operator with constant coefficients of order $n$ and complex eigenvalues $λ_{0}, ..., λ_{n}$ . Assume that the set $U_{n}$ of all solutions of the equ…

Bernstein Operators for Extended Chebyshev Systems

J. M. Aldaz, O. Kounchev, H. Render

Let $U_{n} \subset C^{n} [a, b]$ be an extended Chebyshev space of dimension $n + 1$ . Suppose that $f_{0} \in U_{n}$ is strictly positive and has the property that $…

Shape preserving properties of generalized Bernstein operators on Extended Chebyshev spaces

J. M. Aldaz, O. Kounchev, H. Render

We study the existence and shape preserving properties of a generalized Bernstein operator $B_{n}$ fixing a strictly positive function $f_{0}$ , and a second function $f_{1}$ such t…
