Abstract

Harmonic maps from \BR2\BR^2 or one-connected domain \O\BR2{\O}\subset \BR^2 into GL(m,\BC)GL(m, \BC) and U(m)U(m) are treated. The GBDT version of the B\"acklund-Darboux transformation is applied to the case of the harmonic maps. A new general formula on the GBDT transformations of the Sym-Tafel immersions is derived. A class of the harmonic maps similar in certain ways to line-solitons is obtained explicitly and studied.
