Proof of Fourier Extension Conjecture for Paraboloid
Analysis
Key Takeaways
- •Proves the Fourier extension conjecture for the paraboloid in dimensions greater than 2.
- •Employs a decomposition technique and trilinear equivalences.
- •Uses oscillatory integrals to achieve localization on the Fourier side.
- •Extends the argument to higher dimensions using bilinear analogues.
“The trilinear equivalence only requires an averaging over grids, which converts a difficult exponential sum into an oscillatory integral with periodic amplitude.”
