Bourgain and Demeter: proof of the l² decoupling conjecture

What changed

Proved l2 decoupling for positively curved compact hypersurfaces and the cone.

Scientific scope

The record is the exact two-author 2015 Annals of Mathematics article. The 2014 preprint, later streamlined proofs and separate decoupling or Vinogradov results remain distinct.
