This paper is concerned about the lifespan estimate to the Cauchy problem of semilinear damped wave equations withthe Fujita critical exponent in high dimensions$(n\geq 4)$.We establish the sharp upper bound of the lifespan in the following form T(ε)≤ exp(Cε-2/n),by using the heat kernel as the test function.This is a joint work with Prof.Yi Zhou.
