0 IntroductionRecently, the study of ordinary differential equations in a Banach spacehas been developed extensively by using the strong topology, see [2],13],[4]. Atpresent, however, there is no reference or paper which systematically studiesweak solutions of the Cauchy problem of ordinary differential equation in theweak topology. In references [l],15],[7] and [8], several results of weak solutionsare proved. In this paper, we shall give the other results of weak solutions,some of which are… 相似文献

利用Avery-Henderson不动点定理,讨论了时间测度链上一类非线性边值问题正解的存在性,并在一定条件下得到两个正解的存在性结果,继而利用Legget-Williams不动点定理将其两个正解推广到三个解的情况,同时利用一种等价转化,给出二阶非线性边值问题格林函数的求法,使其求法一般化. 相似文献
