This paper aims to investigate initial-boundary value problem of the nonlinear Tricomi equation on exterior domain in n space dimensions.By introducing appropriate functional and using the Kato lemma,it is deduced that the solution blows up in finite time.In addition,upper bound lifespan estimates of solution are given.
