摘要
The Taub-NUT four-dimensional space-time can be obtained from Euclidean eight-dimensional one through a momentum map construction; the HKLR theorem [9] guarantees the hyperkahler structure of R-8 descends to a hyperkahler structure in the Taub-NUT space. Here we present a detailed and fully explicit construction of the hyperkahler structure of a space-time with a Taub-NUT metric.
