Description

报告摘要:

Riemann’s paper [1] on multi-valued potentials in multiply-connected domains marks arguably the origin of topology. It prompted Lord Kelvin [2] to propose a correction to Green’s first identity in potential theory, but his result remained almost unnoticed. Following Kelvin’s own work we re-derive this result from first principles, and show how ideas and techniques introduced there and then have important implications in modern physics and in current applications of multi-valued gauge theory in condensed matter physics [3].
