Comments on `Existence of axially symmetric solutions in SU(2)-Yang Mills and related theories [hep-th/9907222]'
B. Kleihaus, Jutta Kunz
In [hep-th/9907222] Hannibal claims to exclude the existence of particle-like static axially symmetric non-abelian solutions in SU(2) Einstein-Yang-Mills-dilaton theory. His argume…
Comment on ``Singularities in axially symmetric solutions of Einstein-Yang Mills and related theories, by Ludger Hannibal, [hep-th/9903063]''
B. Kleihaus, J. Kunz
We point out that the statements in [hep-th/9903063] concerning the regularity of static axially symmetric solutions in Yang-Mills-dilaton (YMD) [1] and Einstein-Yang-Mills(-dilato…
Static Regular and Black Hole Solutions with Axial Symmetry in EYM and EYMD theory
B. Kleihaus, J. Kunz
We discuss the recently discovered new class of globally regular and black hole solutions in Einstein-Yang-Mills and Einstein-Yang-Mills-dilaton theory. These asymptotically flat s…
Limiting solutions of sequences of globally regular and black hole solutions in SU(N)-EYMD theories
Abha Sood, Burkhard Kleihaus, Jutta Kunz
Static spherically symmetric solutions in SU(N)-EYM and EYMD theories are classified by the node numbers of their non-trivial gauge field functions. With increasing node numbers, t…
