摘要：It is well known that, in contrast with the Euclidean case, the L2 metric on the moduli space of hyperbolic monopoles is not well defined. It is certainly possible to define a moduli space metric by other means, and there are various proposals in the literature. However whether or not these proposed metrics have any relation with the adiabatic dynamics of hyperbolic monopoles is unclear. To better understand this point, in this talk I describe what the asymptotic behaviour of a metric capturing the dynamics of 2 hyperbolic monopoles should be. The result is derived making used of the point particle approximation and, in analogy with the Euclidean case, the resulting metric is a hyperbolic version of negative mass Taub-NUT. This talk is based on arXiv:2302.13792 in collaboration with Calum Ross.
