Blow up for Systems of Wave Equations in Exterior Domain

Abstract

In this paper the author studies the initial boundary value problem of semilinear wave systems in exterior domain in high dimensions (n ≥ 3). Blow up result is established and what is more, the author gets the upper bound of the lifespan. For this purpose the test function method is used.
