The three-dimensional anisotropic Kakeya--Nikodym conjecture
The three-dimensional anisotropic Kakeya--Nikodym conjecture
Let , let be a strictly convex hypersurface, and let denote the maximal Kakeya--Nikodym estimate referred to in the source as equation (MKNE). Three-dimensional anisotropic Kakeya--Nikodym conjecture. The estimate should hold for every .
The source explains that this conjecture would imply Stein's Fourier restriction conjecture in dimension three. Its status is not resolved in the supplied context.
