The Dirac and Rarita-Schwinger equations on scalar flat metrics of Taub-NUT type
Xiaoman Xue, Chuxiao Liu
We construct a scalar flat metric of Taub-NUT type whose total mass can be negative. The standard Taub-NUT metric and its negative NUT charge counterpart serve as particular exampl…

Geodesics on metrics of self-dual Taub-Nut type
Chuxiao Liu, Qingtao Pu
Geodesic equations are solved when at least two of , , are constant on metrics of self-dual Taub-NUT type. They can also be solved also on self-dual Taub-NUT metrics if o…
