总结 我们研究了 Rn 有界域中双调和 Steklov 特征值问题的谱。我们概括地描述了它的特征,并在域是球的情况下给出了它的显式形式。然后,我们将注意力集中在这个问题的第一个特征值上。我们证明了一些估计并研究了其等周特性。通过回顾一些已知的结果,我们最终强调了仍有待解决的主要开放问题。
Summary We study the spectrum of a biharmonic Steklov eigenvalue problem in a bounded domain of Rn. We characterize it in general and give its explicit form in the case where the domain is a ball. Then, we focus our attention on the first eigenvalue of this problem. We prove some estimates and study its isoperimetric properties. By recalling a number of known results, we finally highlight the main open problems still to be solved.
