多二次和高斯插值的指数型误差界的一个扩展

An Extension of the Exponential-type Error Bounds for Multiquadric and Gaussian Interpolations

Lin-Tian Luh

AI总结:

本文将径向基函数中经典的指数型误差界从函数值误差扩展到导数误差,以适用于偏微分方程中的导数匹配需求。

摘要:

在1990年代,径向基函数理论中出现了指数型误差界。这种误差界非常强大,但它仅衡量逼近函数与被逼近函数之间的差异。在处理偏微分方程时,数学家和工程师通常需要知道导数的匹配情况。在本文中,我们将这种误差界扩展到一种形式,用于衡量逼近函数与被逼近函数的导数之间的差异。

英文摘要:

In the 1990's exponential-type error bounds appeared in the theory of radial basis functions. This kind of error bounds is very powerful. However it only measures the difference between the approximant and approximand. Mathematicians and engineers often need to know the matching of the derivatives when dealing with partial differential equations. In this paper we extend this kind of error bounds to a form which measures the difference between the derivatives of the approximant and approximand.
