中文摘要: |
在这篇文章中,我们研究四阶半线性热方程在已给初边界条件下解的爆破,我们利用凸性方法证明了上述问题的解,在有限时内变为无穷,假若α(x,t),αij(x),f(u,△tu)与初边值满足某些条件. |
英文摘要: |
In this paper, we study the blow-up of the solution of the fourth-order semilinear heat equationwith given initial and boundary condition . Using concavity method, we proved that che solution of above problems become infinite in finite time, provided a(x,t) , aij(x) , f(u,Δtu) and initial-boundary-value satisfy some conditions . |
