中文摘要
研究了一类非线性常微分方程的两点边值问题。建立了变号解唯一性的新结果。作为它的应用,我们得到了球内椭圆型偏微分方程边值问题变符号径向解唯一性的充分条件。此外,还给出了变符号径向解的非唯一性例子。利用本文的方法,可以得到两点边值问题变符号解的精确多重性结果。
英文摘要
In this study, two-point boundary value problems for nonlinear ordinary differential equations are considered. New results for the uniqueness of sign-changing solutions are established. As its application we have obtained sufficient conditions for the uniqueness of sign-changing radial solutions of boundary value problems of elliptic partial differential equations in a ball. Moreover the nonuniqueness examples for sign-changing radial solutions are also given. It is expected that we can obtain exact multiplicity results for sign-changing solutions of two-point boundary value problems by applying the method used here.
