$\mathbb{R}^3$中的非线性卷曲-卷曲问题

Nonlinear curl-curl problems in $\mathbb{R}^3$

Jarosław Mederski, Jacopo Schino

摘要:

本文综述了近年来关于非线性Maxwell方程组的卷曲-卷曲问题$$\nabla\times(\nabla\times u)+V(x)u= f(x,u) \quad\hbox{ in } \mathbb{R}^3,$$的基态和束缚态$u\colon\mathbb{R}^3\to\mathbb{R}^3$的研究结果。由于$\nabla\times(\nabla\times \cdot)$的无穷维核,与此问题相关的能量泛函是强不确定的。增长的非线性$f$是超线性和亚临界在无穷大或纯临界,我们证明了一个变分方法的问题,涉及广义Nehari流形。我们还提出了一些已知结果的改进。

英文摘要:

We survey recent results concerning ground states and bound states $u\colon\mathbb{R}^3\to\mathbb{R}^3$ to the curl-curl problem $$\nabla\times(\nabla\times u)+V(x)u= f(x,u) \quad\hbox{ in } \mathbb{R}^3,$$ which originates from the nonlinear Maxwell equations. The energy functional associated with this problem is strongly indefinite due to the infinite dimensional kernel of $\nabla\times(\nabla\times \cdot)$. The growth of the nonlinearity $f$ is superlinear and subcritical at infinity or purely critical and we demonstrate a variational approach to the problem involving the generalized Nehari manifold. We also present some refinements of known results.
