Theorems in analysis | Inequalities
In mathematical analysis, Strichartz estimates are a family of inequalities for linear dispersive partial differential equations. These inequalities establish size and decay of solutions in Lebesgue spaces. They were first noted by Robert Strichartz and arose out of connections to the Fourier restriction problem. (Wikipedia).
D. Oliveira e Silva: Some Sharp Strichartz Inequalities
Abstract: It has long been understood that Strichartz estimates for the homogeneous Schrödinger equation correspond to adjoint Fourier restriction estimates on the paraboloid. The study of extremizers and sharp constants for the corresponding inequalities has a short but rich history. In t

Roland Donninger: Strichartz estimates for the one-dimensional wave equation
Abstract: I will report on work in progress with Irfan Glogic on one-dimensional wave evolution in hyperboloidal coordinates. We prove a set of Strichartz estimates for equations perturbed by a general potential. I will also outline possible applications, e.g. Yang-Mills fields on wormhole

Sagun Chanillo: Borderline Sobolev Inequalities on Symmetric Spaces with Applications
The lecture was held within the framework of the Hausdorff Trimester Program: Evolution of Interfaces. Abstract: Bourgain and Brezis proved the following remarkable estimate: Consider the equation, −∆u = f where f : R^n → R^n is a vector field with zero divergence. Further u : R^n → R^n an

Piero D'ANCONA - Equivariant wave maps on a class of rotationally symmetric manifolds
Joint work with Qidi Zhang (Shanghai). We study a class of rotationally invariant manifolds, which we call admissible, on which it is possible to prove smoothing and Strichartz estimates for the wave equation. This class includes asymptotically flat manifolds but

Modulation Spaces and Applications to Hartree-Fock Equations by Divyang Bhimani
We discuss some ongoing interest (since last decade) in use of modulation spaces in harmonic analysis and its connection to nonlinear dispersive equations. In particular, we shall discuss results on Hermite multiplier and composition operators on modulation spaces. As an application to the

Fabrice Planchon: The wave equation on a model convex domain revisited
Abstract: We detail how the new parametrix construction that was developped for the general case allows in turn for a simplified approach for the model case and helps in sharpening both positive and negative results for Strichartz estimates. Recording during the thematic meeting "French-A

In this video (which I made up on the spot!), I calculate the Stieltjes integral of x from 0 to 1 with alpha(x) = x^2. That integral is a nice generalization of the Riemann integral and closely resembles it. Then I show how those integrals are similar in the case alpha is smooth, and final
