摘要

我们考虑Moore-Nehari方程，u′′′+h（x，λ）|u|p−1u=0在（−1，1）中，u（−1）=u（1）=0，其中p>1，h（x、λ）=0对于|x|<λ，h（x、λ）=1对于λ≤|x|≤1，λ∈（0，1）是一个参数。对于给定的非负整数m和n，我们证明了一个解的存在性，该解在区间（−1，0）中正好有m个零，在区间（0，1）中恰好有n个零。

Symmetric and asymmetric nodal solutions for the Moore–Nehari differential equation

We consider the Moore-Nehari equation, u′′+h(x, λ)|u|p−1u = 0 in (−1, 1) with u(−1) = u(1) = 0, where p > 1, h(x, λ) = 0 for |x| < λ, h(x, λ) = 1 for λ ≤ |x| ≤ 1 and λ ∈ (0, 1) is a parameter. We prove the existence of a solution which has exactly m zeros in the interval (−1, 0) and exactly n zeros in (0, 1) for given nonnegative integers m and n.

期刊介绍： The Journal of the Mathematical Society of Japan (JMSJ) was founded in 1948 and is published quarterly by the Mathematical Society of Japan (MSJ). It covers a wide range of pure mathematics. To maintain high standards, research articles in the journal are selected by the editorial board with the aid of distinguished international referees. Electronic access to the articles is offered through Project Euclid and J-STAGE. We provide free access to back issues three years after publication (available also at Online Index).
