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. Examples Consider the linear Schrödinger equation in with h = m = 1. Then the solution for initial data is given by . Let q and r be real numbers satisfying ; ; and . In this case the homogeneous Strichartz estimates take the form: Further suppose that satisfy the same restrictions as and are their dual exponents, then the dual homogeneous Strichartz estimates take the form: The inhomogeneous Strichartz estimates are: References Theorems in analysis Inequalities
