Abstract
In this paper we establish Lp - Lq estimates for the solution of the strictly hyperbolic first-order linear systems with bounded time-dependent coefficients. In the equation setting, Reissig and others obtained such estimates by using WKB representations of the solutions. Here the crucial point is to nd minimal assumptions on the coefficients of the system so that Reissig's approach still works for systems.File in questo prodotto:
