经典多项式空间上的广义Bernstein算子

Generalized Bernstein operators on the classical polynomial spaces

J. M. Aldaz, H. Render

摘要:

本文研究了多项式空间上经典Bernstein算子的推广,其中不要求固定$\mathbf{1}$和$x$,而是要求固定$\mathbf{1}$和严格递增多项式$f_1$.通过几个例子,我们展示了在这个更一般的设置行为的多样性。证明了在足够大的维数下,总存在广义Bernstein算子固定$\mathbf{1}$和$f_1$,并收敛于恒等式.

英文摘要:

We study generalizations of the classical Bernstein operators on polynomial spaces, where instead of fixing $\mathbf{1}$ and $x$, we require that $\mathbf{1}$ and a strictly increasing polynomial $f_1$ be fixed. Via several examples, we exhibit the diversity of behaviours in this more general setting. We also prove that for sufficiently large dimensions, there always exist generalized Bernstein operators fixing $\mathbf{1}$ and $f_1$, and converging to the identity.
