Geometric spectral theory is an area of mathematics that lies at the intersection of analysis, partial differential equations and differential geometry. To a large extent, it is motivated by questions originating in the study of real life phenomena, such as vibration, heat propagation, oscillations of fluids and quantum mechanical effects. The first part of the proposal is concerned with the spectral geometry of the Steklov problem. This eigenvalue problem, introduced by V. Steklov in 1902, has many important applications, but is still relatively unexplored by pure mathematicians. The proposed topics of research include the study of singular Steklov type problems, such as the sloshing problem; isospectrality and spectral invariants; nodal geometry of Steklov eigenfunctions. The second part of the proposal focuses on some questions arising in the study of spectral asymptotics of Laplace and Schrodinger operators.* *

几何谱理论是一个数学领域，位于分析，偏微分方程和微分几何的交叉点。在很大程度上，它的动机是源于对现实生活现象的研究，如振动、热传播、流体振荡和量子力学效应。第一部分讨论了Steklov问题的谱几何。这个特征值问题是由V. Steklov在1902年提出的，它有许多重要的应用，但相对来说还没有被纯数学家探索过。提出的研究课题包括奇异Steklov型问题的研究，如晃动问题；等谱性与谱不变量；Steklov特征函数的节点几何。第二部分着重讨论了拉普拉斯算子和薛定谔算子谱渐近研究中出现的一些问题。* *
