Fourier coefficients of restrictions of eigenfunctions

Emmett L. Wyman, Yakun Xi, Steve Zelditch

Let ${e_{j}}$ be an orthonormal basis of Laplace eigenfunctions of a compact Riemannian manifold $(M, g)$ . Let $H \subset M$ be a submanifold and let ${ψ_{k}}$ be an orthonormal bas…

Square function estimates and Local smoothing for Fourier Integral Operators

Chuanwei Gao, Bochen Liu, Changxing Miao +1

We prove a variable coefficient version of the square function estimate of Guth--Wang--Zhang. By a classical argument of Mockenhaupt--Seeger--Sogge, it implies the full range of sh…
