Higher order neck analysis of harmonic maps and its applications

Published 15 Apr 2019 in math.DG and math.AP | (1904.07354v1)

Abstract: In this paper, we prove some refined estimate in the neck region when a sequence of harmonic maps from surfaces blow up. The new estimate allows us to see the shape of the center of the neck region. As an application, we prove an inequality about the nullity and index when blow-up occurs.
