AbstractMargulisThe problems to be investigated are in the area of the theory of Lie groups and their discrete subgroups. One of the main objectives is to continue the program of establishing a homogeneous space approach as a powerful tool in number theory. Special attention will be given to the problem of "effectivization" in Oppenheim conjecture and its quantitative generalizations. It is also proposed to continue to study recurrence properties of random walks on Lie groups and their discrete subgroups on homogeneous spaces, manifolds and general metric spaces.The theory of Lie groups and their discrete subgroups is one of the central fields in mathematics. During the last few decades, it was realized that some aspects of the theory can be applied to solve certain problems in number theory and related topics, which could not be tackled by other methods. This proposal is related to rigidity theory that studies phenomena when rather weak data about geometric and mathematical objects determines completely or almost completely the structure of those objects.

摘要margulis将要研究的问题在谎言群体及其离散亚组的理论领域。 主要目标之一是继续建立同质空间方法作为数字理论中强大的工具的程序。 在Oppenheim猜想及其定量概括中，将特别注意“有效化”的问题。 还建议继续研究在谎言组上随机步行的复发特性及其在同质空间，歧管和一般度量空间上的离散亚组。谎言组及其离散亚组的理论是数学中的中心领域之一。 在过去的几十年中，人们意识到该理论的某些方面可以应用于数字理论和相关主题中的某些问题，而其他方法无法解决这些问题。 该建议与刚性理论有关，即当关于几何和数学对象的较弱数据完全或几乎完全决定这些对象的结构时，研究现象。
