摘要
对于二元非乘积型Lupas-Baskakov算子,结合逼近论和概率论的知识讨论该算子的极限,运用多元算子分解技巧得到该算子逼近的Voronovskaja型展式.
Using the knowledge of probability and approximation theories, the limits of two-dimensional non-product-type Lupas-Baskakov operators were discussed. And by means of decomposition technique for multicomponent operators, the Voronovskaja-type expansion of approximation was obtained.
