| Abstract： |
In this paper the author studies the initial boundary value problem of semilinear wave
systems in exterior domain in high dimensions ($n\geq 3$). 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. |
