柱体内半线性偏微分方程的单调解及其应用

Monotone heteroclinic solutions to semilinear PDEs in cylinders and applications

Fabio De Regibus, David Ruiz

AI总结:

本文证明柱体内半线性椭圆方程存在严格单调异宿型解,由此构造出非一维的无临界点整体有界解及非剪切流的二维欧拉方程平稳解,完善了先前结果。

摘要:

本文证明了柱体内半线性椭圆方程严格单调异宿型解的存在性。此构造的动机有二:其一,它意味着存在一个非一维的、无临界点的半线性方程整体有界解;其二,这为二维欧拉方程提供了一个无驻点的有界平稳解的例子,该解不是剪切流,从而完善了Hamel和Nadirashvili的先前结果。证明采用了极小化技术、截断论证以及极限过程。

英文摘要:

In this paper we show the existence of strictly monotone heteroclinic type solutions of semilinear elliptic equations in cylinders. The motivation of this construction is twofold: first, it implies the existence of an entire bounded solution of a semilinear equation without critical points which is not one-dimensional. Second, this gives an example of a bounded stationary solution for the 2D Euler equations without stagnation points which is not a shear flow, completing previous results of Hamel and Nadirashvili. The proof uses a minimization technique together with a truncation argument, and a limit procedure.
