Abstract

We consider the problem (formula presented) with nonnegative, nontrivial, continuous initial condition, (formula presented) An integral inequality is obtained that can be used to find an exponent p_c such that this problem has no nontrivial global solution when p ≤ p_c. This integral inequality may also be used to estimate the maximal T > 0 such that there is a solution for 0 ≤ t < T. This is illustrated for the case ρ ≡ 1 and h ≡ 1 with initial condition u(x, 0) = σu₀(x), σ > 0, by obtaining a bound of the form T ≤ C₀σ^-θ.
