Frechet

基本解释

Domain derivative is a new tool to solve inverse problem, which bases on Frechet derivative to recover the shape of domain using the differentiability of the operator.
首先把区域导数的概念引入到流体力学方程上来。
Some inaccurated definitions and properties in text [1, 2] are introduced and reformed. The definition of infinite space, cover Frechet (v) spaces, net cover spaces and their property are discussed.
