摘要:The V-harmonic map is a natural generalization of the harmonic map, but lack of a variational structure in general. We find that when V is conformal, the evolution and blow-up of 2d V-harmonic map flow still share same properties with the ordinary harmonic map flow. In particular, the finite-time singularities must locate at zeroes of V when the blow-up rate is sufficiently slow.
