Wu-Yang Monopoles and Non-Abelian Seiberg-Witten Equations
Some exact solutions of the SU(2) Seiberg-Witten equations in Minkowski spacetime are given.
متن کاملAspherical Gravitational Monopoles
We show how to construct non-spherically-symmetric extended bodies of uniform density behaving exactly as pointlike masses. These “gravitational monopoles” have the following equivalent properties: (i) they generate, outside them, a spherically-symmetric gravitational potential M/|x − xO| ; (ii) their interaction energy with an external gravitational potential U(x) is −M U(xO) ; and (iii) all t...
متن کاملStatic Gravitational Global Monopoles
Topological defects have attracted quite a bit of attention because of their relevance to a number of different areas ranging from condensed matter to structure formation. Studies of global monopoles in particular have served as a foundation on which knowledge of other defects has been built. Previous work details static gravitating global monopole solutions [1,2], while further studies conside...
متن کاملDirac and Yang monopoles revisited
The Dirac monopoles in 3-space and their generalization by C. N. Yang to 5-space are observed to be just the Levi-Civita spin connection of the cylindrical Riemannian metric on the 3and 5dimensional punctured spaces. Their straightforward generalization to higher dimensions is also investigated.
متن کاملWu-yang Ambiguity in Connection Space
A good understanding of the Wu-Yang ambiguity [1], with all its aspects and consequences, does not seem to have been as yet achieved. Activity on the subject has been intensive in the first years after its discovery [2, 3, 4, 5, 6, 7] and declined afterwards [8]. Progress has been made step by step, sometimes through the discovery of general properties of formal character [9], most of times by ...
