ENERGY QUANTIZATION OF WILLMORE SURFACES AT THE BOUNDARY OF THE MODULI SPACE

摘要

We establish an energy quantization result for sequences of Willmore surfaces when the underlying sequence of Riemann surfaces is degenerating in the moduli space. We notably exhibit a new residue which quantifies the possible loss of energy in collar regions. Thanks to this residue, we also establish the compactness (modulo the action of the Mobius group of conformal transformations of R-3 U {infinity}) of the space of Willmore immersions of any arbitrary closed 2-dimensional oriented manifold into R-3 with uniformly bounded conformal class and energy below 12 pi.
