摘要:

研究具浓度相关黏性系数的黏性Cahn-Hilliard方程解的爆破性质. 利用能量估计方法, 在关于黏性系数的两个不同结构性条件下分别证明了初边值问题的解在有限时刻爆破和时间趋于无穷时解趋于无穷两个性质. 结果表明, 黏性系数所满足的结构性条件对于方程的解有较大影响.

关键词: 爆破, 黏性Cahn-Hilliard方程, 浓度相关黏性系数

Abstract:

We studied the blowup of the solutions to the viscous CahnHilliard equation with concentration dependent viscosity. The results  show that the structural conditons satisfied by the coefficient of viscosity play an important role in the properties of the solutions. Under two different structural conditions of the coefficient of viscosity, using the energy method, we proved  that the solutions of the initial boundary value problem blow up in finite time or tend to infinity as t→+∞.

Key words: blowup, viscous CahnHilliard equation, concentration dependent viscosity
