【摘要】 J.L.L ions用紧致性方法证明了一类退化非线性抛物型方程初边值问题整体解的存在唯一性,但解的衰减性很少有人考虑.应用M.N akao建立的差分不等式研究了整体解的衰减估计.更多还原

【Abstract】 J.L.Lions has proved the existence and uniqueness of global solutions to the initial-boundary value problem for a class of nonlinear degenerate parabolic equation by mean of compactness principle,but the decay property is considered by few people.In this paper,we study the decay estimate of global solutions making use of the difference inequality being established by M.Nakao.更多还原
