Yang--Mills Monopoles in Extremal Reissner--Nordström Black Hole Metric
Xiangqin Zhang, Yisong Yang
We show that the closed-form monotone solution linking two different vacuum states, for the exterior Yang--Mills wave equation over the extremal Reissner--Nordström spacetime found…

Solutions to the Minimization Problem Arising in a Dark Monopole Model in Gauge Field Theory
Xiangqin Zhang, Yisong Yang
We prove the existence of dark monopole solutions in a recently formulated Yang--Mills--Higgs theory model with technical features similar to the classical monopole problems. The s…
