摘要
通过构造合适的控制函数,利用能量估计法并结合Gronwall不等式的讨论,研究具变指数源函数的非牛顿多方渗流方程解的爆破性质.结果表明,当初始能量为正时,解在有限时刻爆破.
The authors studied blow-up properties of solutions to a polytropic filtration equation with variable exponent of nonlinearity,By constructing a suitable control function,applying energy estimates method and Gronwall's inequalities,we proved that the solution of the above problem blows up in finite time wher the initial energy is positive.
