The order of curvature operators on loop groups
arXiv:0909.4466 · doi:10.1007/s11005-009-0352-1
Abstract
For loop groups (free and based), we compute the exact order of the curvature operator of the Levi-Civita connection depending on a Sobolev space parameter. This extends results of Freed and Maeda-Rosenberg-Torres.
