Topological Solitons Seminar: Monopoles and "hairy" black holes

Presented by Betti Hartmann,

23 October 2002 00:00 in CM221

"In this talk I will review what is known about classical solutions of SU(2) Yang-Mills-Higgs theories in both flat and curved space. The flat space solutions are the famous 't Hooft-Polyakov magnetic monopole and its higher winding number generalisations. When gravity comes into play basically three different types of solutions are possible: a) globally regular gravitating monopoles, b) abelian black holes which are uniquelly described by their mass and magnetic charge and c) non-abelian, so-called "hairy" black holes which unlike b) are NOT uniquelly described by their mass and charge. I will put emphasis on my contribution to the topic, namely the construction of axially symmetric solutions, which involves the solving of systems of partial differential equations."
