We establish direct estimates of the rate of weighted simultaneous approximation by the Szasz–Mirakjan operator for smooth functions in the supremum norm on the non-negative semi-axis. We consider Jacobi-type weights. The estimates are stated in terms of appropriate moduli of smoothness or K-functionals.

Szász-Mirakjan 算子对加权同时近似的直接估计

我们通过 Szasz-Mirakjan 算子建立了对非负半轴上最高范数中的平滑函数的加权同时逼近率的直接估计。我们考虑 Jacobi 类型的权重。估计值以适当的平滑度或 K 函数模数表示。
