利用能量泛函的方法,研究了方程ut-div(|▽u|p(x)-2▽u)=f(u)(x∈Ω,t>0)在正初始能量下解的爆破问题。在对f的增长阶等条件作了一定的限制情况下,证明了该方程的能量泛函在时间t*处趋于无穷,因此,方程的解在有限时间内爆破。
- Abstract:
-
The problem ut-div(|▽u|p(x)-2▽u)=f(u)(x∈Ω,t>0)with the method of energy functional was considered.A blow-up result for certain solution with positive initial energy was established.If some restrictions of the growth order of f are imposed,it was proved that equation of the energy functional in time t*tends to infinity,so the solution blow -up in a limited time.
