摘要：
Applying the harmonic map ansatz we find new classes of SU(N) and SO(N) chiral fields. We write the corresponding one- dimensional subgroups of SU(N) and SO(N) chiral fields in terms of one and two harmonic maps and the corresponding two-dimensional subgroups in terms of SU(2) and SO(3) chiral fields. In other words, we reduce the SU(N) and SO( N) chiral equations to harmonic maps in one- and two-dimensional spaces. (C) 1999 American Institute of Physics. [S0022-2488(99)01204-9].
