We investigate the convergence of entire Lagrange interpolations and of Hermite interpolations of exponential type \(\tau \), as \(\tau \rightarrow \infty \), in weighted \(L^p\)-spaces on the real line. The weights are reciprocals of entire functions that depend on \(\tau \) and may be viewed as smoothed versions of a target weight w. The convergence statements are obtained from weighted Marcinkiewicz inequalities for entire functions. We apply our main results to deal with power weights.

加权空间中整个插值的平均收敛性

我们研究了整个拉格朗日插值和指数类型\(\tau \)的 Hermite 插值的收敛性,如\(\tau \rightarrow \infty \),在实线上的加权\(L^p\) -空间中。权重是依赖于\(\tau \)的整个函数的倒数,可以被视为目标权重w 的平滑版本。收敛性陈述是从整个函数的加权 Marcinkiewicz 不等式中获得的。我们应用我们的主要结果来处理功率权重。
