Global regularity of wave maps VI. Abstract theory of minimal-energy blowup solutions

Abstract

In the previous papers in this series, the global regularity conjecture for wave maps from two-dimensional Minkowski space ${\mathbb{R}}^{1+2}$ to hyperbolic space $\H^m$ was reduced to the problem of constructing a minimal-energy blowup solution which is almost periodic modulo symmetries in the event that the conjecture fails. In this paper, we show that this problem can be reduced further, to that of showing that solutions at the critical energy which are either frequency-delocalised, spatially-dispersed, or spatially-delocalised have bounded ``entropy''. These latter facts will be demonstrated in the final paper in this series.

36 pages, no figures. Will not be published in current form, pending future reorganisation of the heatwave project
