We derive a number of analytic and geometric conditions under which harmonic maps are constant and which force biharmonic maps to be harmonic. In particular, we show that biharmonic maps of finite energy from the two-dimensional cigar soliton must be harmonic.Ricci solitonsAncient solutionsSurfacesHarmonic maps & DeTurck trick
