本文利用单调算子理论,证明扩散现象中出现的一类非线性退缩抛物型方程初边值问题广义解的存在唯一性和非负性,所得结果推广和改进了Nakao的结果.
Abstract:This paper discusses the existence,uniqueness and nonnegativity of solutions to thenon-linear degenerate parabolic equations by using the theorem of compactness and monotonic opera-tor.The results of this papor have improved the one of Nakao.
