Abstract:

In this talk, I will introduce the Three circle lemma of harmonic functions and give its applications in some geometric variational problems, such as harmonic maps, Dirac-harmonic maps and biharmonic maps. Specially, I will prove energy identity and no neck property for a blowup sequence of these maps.
