摘要:
本文研究了单位超立方体上所有Lebesgue可积函数空间上定义的依赖于一个非负整数参数的多元Stancu-Kantorovich算子。我们证明了$L^{p}$ -近似和提供估计的$L^{p}$ -范数的逼近误差的多元平均模的连续性和相应的$L^{p}$ -模。
英文摘要:
We deal with multivariate Brass-Stancu-Kantorovich operators depending on a non-negative integer parameter and defined on the space of all Lebesgue integrable functions on a unit hypercube. We prove $L^{p}$-approximation and provide estimates for the $L^{p}$-norm of the error of approximation in terms of a multivariate averaged modulus of continuity and of the corresponding $L^{p}$-modulus.
