Strichartz inequality
WebStrichartz estimates are spacetime estimates on homogeneous and inhomogeneous linear dispersive and wave equations. They are particularly useful for solving semilinear perturbations of such equations, in which no derivatives are present in the nonlinearity. WebThis is the sharp Strichartz inequality (5) for k= 1 proven by Foschi. Note that equality is attained if and only if fb2E, which in turn is equivalent to gbeing a Gaussian4. Let H ndenote the space of spherical harmonics of degree non the (d 1)-dimensional unit sphere Sd 1 (i.e., the restrictions to Sd 1 of degree nhomogeneous polynomials ...

WebJSTOR 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.
Web1. The Strichartz inequality The goal for the next couple lectures is to understand the Strichartz inequality for the Schrodinger equation. After that, we will start to study non-linear Schrodinger equations, and we will see that the Strichartz inequality plays an important role there. We stated the Strichartz inequality a couple weeks ago.
