利用抛物正则化方法及上下解方法、Fatou引理等,研究了一类带梯度项奇异抛物方程非负古典解,得到了该解的存在性及相应的渐近行为.
Using parabolic regularization method,sub-super solution method and Fatou Lemma etc.,we discuss nonnegative classical solutions of some singular parabolic equation with gradient term,existence and asymptotic behavior of the solutions are obtained.
