Generalized Strichartz Inequalities for the Wave Equation

WebParticularly when r = r ˜, Theorem 1.3 covers the classical Strichartz estimates except for the endpoint case q = 2. In fact, we further obtain (1.6) for the endpoint case when the first inequality in (1.5) holds strictly. If not, it can be also obtained by making use of the Keel-Tao's bilinear argument. WebJun 6, 2013 · We prove a Strichartz inequality for a system of orthonormal functions, with an optimal behavior of the constant in the limit of a large number of functions. The estimate generalizes the usual Strichartz inequality, in the same fashion as the Lieb-Thirring inequality generalizes the Sobolev inequality. As an application, we consider the … WebThe Strichartz inequality for orthonormal functions Rupert L.

WebWe analyze the dispersive properties of a Dirac system perturbed with a magnetic field. We prove a general virial identity; as applications, we obtain smoothing and endpoint Strichartz estimates which are optimal from the decay point of view. We also prove a Hardy-type inequality for the perturbed Dirac operator.

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 mixed norm Lebesgue spaces. They were first noted by Robert Strichartz and arose out of connections to the Fourier restriction problem.
