Non-abelian self-dual string solutions

Non-Abelian String Conductivity

We examine current-carrying configurations of cosmic strings in non-Abelian gauge theories. We study the solutions numerically and point out that the currents will be at best dynamically stable and not subject to any topological quantisation or conservation, as in conventional models of string superconduction. We suggest that non-Abelian string loops may be unable to support persistent currents...

BFT Hamiltonian Embedding of Non-Abelian Self-Dual Model

Following systematically the generalized Hamiltonian approach of Batalin, Fradkin and Tyutin, we embed the second-class non-abelian self-dual model of P. K. Townsend et al into a gauge theory. The strongly involutive Hamiltonian and constraints are obtained as an infinite power series in the auxiliary fields. By formally summing the series we obtain a simple interpretation for the first-class H...

Abelian and Non–Abelian Dualities in String Backgrounds

We present a brief discussion of recent work on duality symmetries in non–trivial string backgrounds. Duality is obtained from a gauged non–linear σ–model with vanishing gauge field strength. Standard results are reproduced for abelian gauge groups, whereas a new type of duality is identified for non–abelian gauge groups. Examples of duals of WZW models and 4–d black holes are given. String The...

The Self - Dual String Soliton

We obtain a BPS soliton of the M theory fivebrane's equations of motion representing a supersymmetric self-dual string. The resulting solution is then dimensionally reduced and used to obtain 0-brane and (p − 2)-brane solitons on D-p-branes.
