摘要 研究了具有齐次Dirichlet边界和变指标反应项的非线性双曲方程u_t-div(|▽u |^(p-2)▽u)=|▽u |^(q(x))(p>2)在(x,t)∈Ω×(0,T)(T>0)内非负解的爆破性质,并运用特征函数方法得到方程解在有限时刻爆破的条件。 The blow-up property of nonnegative solutions is studied for the following nonlinear hyperbolic equation: u_t,-div(|▽u|^([-2)▽u) = |▽u |^(q(x))(p > 2) with homogeneous Dirichlet boundary conditions and variable reaction in(x,t)∈Ω×(0,T)(T> 0).By using the eigenfunction method,the condition of blow-up in a finite time is obtained.
