Abelyen olmayan manyetik monopol ve dyonlar

We first review Dirac's Abelian magnetic monopole solutions in Maxwell's electrodynamics.Then after a short discussion of the unified electroweak gauge fiield theories and the Higgsmechanism for mass generation we derived the non-Abelian magnetic monopole solutions of't Hooft and Polyakov. We discussed the topological nature of such solutions. We calculatedthe total mass and the magnetic charge of these solutions and verified that they saturatethe BPS bound. Dyon solutions are also given. Finally, we briefly comment on Montonenand Olive's non-Abelian duality conjecture.
