Exact solutions ofG-invariant chiral equations
- 54 Downloads
A method is suggested for solving the chiral equations (αg,zg−1),¯z+(αg,¯zg−1),z=0, whereg belongs to some Lie groupG. The solution is written out in terms of harmonic maps. The method can be used even for some infinite-dimensional Lie groups.
