欧几里得空间中的半变分不等式

Some hemivariational inequalities in the Euclidean space

Giovanni Molica Bisci, Dušan D. Repovš

摘要:

本文研究了欧几里得空间$\mathbb{R}^d$($d\geq 3$)中几类半变分问题弱解的存在性.这些半变分不等式有变分结构,由于这一点,我们能够找到一个非平凡的弱解,他们使用变分方法和非光滑版本的Palais原则的对称临界局部Lipschitz连续泛函,由于Krawcewicz和Marzantowicz。在我们的方法中的主要工具是基于适当的理论参数的正交群$O(d)$和他们的行动上的Sobolev空间$H^1(\mathbb{R}^d)$的合适的子群。在对维数$d$的一个附加假设下,在非线性数据具有对称性的情况下,证明了多对具有不同对称结构的变号解的存在性.结合经典的薛定谔方程给出了一个具体而有意义的应用实例。

英文摘要:

The purpose of this paper is to study the existence of weak solutions for some classes of hemivariational problems in the Euclidean space $\mathbb{R}^d$ ($d\geq 3$). These hemivariational inequalities have a variational structure and, thanks to this, we are able to find a non-trivial weak solution for them by using variational methods and a non-smooth version of the Palais principle of symmetric criticality for locally Lipschitz continuous functionals, due to Krawcewicz and Marzantowicz. The main tools in our approach are based on appropriate theoretical arguments on suitable subgroups of the orthogonal group $O(d)$ and their actions on the Sobolev space $H^1(\mathbb{R}^d)$. Moreover, under an additional hypotheses on the dimension $d$ and in the presence of symmetry on the nonlinear datum, the existence of multiple pairs of sign-changing solutions with different symmetries structure has been proved. In connection to classical Schrödinger equations a concrete and meaningful example of an application is presented.
