On Sharp Strichartz Inequalities in Low Dimensions

چکیده
Recently Foschi gave a proof of a sharp Strichartz inequality in one and two dimensions. In this note, a new representation in terms of an orthogonal projection operator is obtained for the space time norm of solutions of the free Schrödinger equation in dimension one and two. As a consequence, the sharp Strichartz inequality follows from the elementary property that orthogonal projections do not increase the norm.

Maximizers for the Strichartz Inequalities and the Sobolev-strichartz Inequalities for the Schrödinger Equation
In this paper, we first show that there exists a maximizer for the non-endpoint Strichartz inequalities for the Schrödinger equation in all dimensions based on the recent linear profile decomposition results. We then present a new proof of the linear profile decomposition for the Schröindger equation with initial data in the homogeneous Sobolev space; as a consequence, there exists a maximizer ...
متن کاملSharp Strichartz Estimates on Non-trapping Asymptotically Conic Manifolds
We obtain the Strichartz inequalities Lt Lx([0,1]×M) ≤ C‖u(0)‖L2(M) for any smooth n-dimensional Riemannian manifold M which is asymptotically conic at infinity (with either short-range or long-range metric perturbation) and non-trapping, where u is a solution to the Schrödinger equation iut + 1 2 ∆Mu = 0, and 2 < q, r ≤ ∞ are admissible Strichartz exponents ( 2 q + n r = n 2 ). This correspond...
متن کاملSharp Counterexamples for Strichartz Estimates for Low Regularity Metrics
On the other hand, in [3] there were constructed for each α < 1 examples of A with coefficients of regularity C for which the same estimates fail to hold. The first author then showed in [1] that, in space dimensions 2 and 3, the estimates do hold if the coefficients of A are C. The second author subsequently showed in [4] that the estimates hold for C metrics in all space dimensions, and that ...
متن کاملOrthogonal Polynomials and Sharp Strichartz Estimates
Orthogonal polynomials have been used to produce sharp estimates in Harmonic Analysis in several instances. The first most notorious and original use was in Beckner’s thesis [1], where he proved the sharp Hausdorff-Young inequality using Hermite polynomial expansions. More recently, Foschi [4] used spherical harmonics and Gegenbauer polynomials in his proof of the sharp Tomas-Stein adjoint Four...
متن کاملOn Strichartz and Eigenfunction Estimates for Low Regularity Metrics
A bstract . We produce, for dimensions n ≥ 3, examples of wave operators for which the Strichartz estimates fail. The examples include both Lipschitz and C1,α metrics, for each 0 < α < 1, where by the latter we mean that the gradient satisfies a Hölder condition of order α. We thus conclude that, on the scale of Hölder regularity, an assumption of at least 2 bounded derivatives for the metric (...
