摘要
探讨非线性抛物型方程组在非线性流量边界条件下的初边值问题.利用上下解方法和杨格不等式,证明了x=1是方程组的惟一熄灭点,给出了解在有限时间熄灭的充分条件.在一定条件下,得到了解的熄灭速率.
The initial boundary value problem of nonlinear parabolic system coupled at the boundary through a nonlinear flux is considered.Upper and lower solutions technique and Young inequality were used,the only quenching point is the origin x=1 was obtained.Sufficient conditions about the quenching of solutions are given.The quenching rates under some assumptions are obtained.
