一类拟线性抛物型方程解的爆破时间的下界(英文)
LOWER BOUND FOR THE BLOW-UP TIME OF THE SOLUTION TO A QUASI-LINEAR PARABOLIC PROBLEM
【摘要】 本文巧妙应用广义Sobolev不等式,研究了一类拟线性抛物型方程解的爆破时间的下界,该结果推广了文献[1]中的定理2.1和定理3.1的结论,同样完善了文献[2]中的模型(4.1)的结论.
【Abstract】 In this paper,using a delicate application of general Sobolev inequality,we establish the lower bound for the blow-up time of the solution to a quasi-linear parabolic problem,which improves the result of Theorem 2.1,Theorem 3.1 in [1],and the model(4.1) in [2].
