莫比乌斯变换及其物理应用

Mbius Transform and Its Applications in Physics

北京科技大学陈难先教授把数论中的一条古老定理：莫比乌斯变换推广到普通函数并创造性地用之于物理学中许多反问题，取得了巨大成功。在此以更直观和易于理解的方式导出陈氏定理，并通过一些具体实例展示其应用前景。

Mbius inverse formula is an old theorem in number theory. Professor Chen Nanxian extended it to ordinary function and presented a new method for solving many inversion problems in physics. This paper introduces Chen′s theorem with a more comprehensible way and shows its vast range of application prospects by some concrete problems.
