| contents | We prove Lojasiewicz inequalities for the harmonic map energy for maps from surfaces of positive genus into general analytic target manifolds which are close to simple bubble trees and as a consequence obtain new results on the convergence of harmonic map flow and on the energy spectrum of harmonic maps with small energy.
Our results and techniques are not restricted to particular targets or to integrable settings and we are able to lift general Lojasiewicz-Simon inequalities valid near harmonic maps $\hat ω:S^2\to N$ to the singular setting whenever the bubble $\hat ω$ is attached at a point which is not a branch point. |
