Louis Dupaigne, Boyan Sirakov, Philippe Souplet

AI总结:

本文证明了半空间中 Lane-Emden 方程 Dirichlet 问题在法向单调正解的不存在性,解决了长期公开问题,并将结果推广至一般凸非线性项。

摘要:

我们证明了半空间中 Lane-Emden 方程的 Dirichlet 问题不存在在法向单调的正解。因此,该问题不存在任何在有限带上有界的正经典解。此问题历史悠久,我们的结果解决了一个长期悬而未决的公开问题。此前,此类非存在性结果仅对有界解或在非线性项幂次受限时成立。该结果可推广到一般的凸非线性项。

英文摘要:

We prove that the Dirichlet problem for the Lane-Emden equation in a half-space has no positive solution which is monotone in the normal direction. As a consequence, this problem does not admit any positive classical solution which is bounded on finite strips. This question has a long history and our result solves a long-standing open problem. Such a nonexistence result was previously available only for bounded solutions, or under a restriction on the power in the nonlinearity. The result extends to general convex nonlinearities.
