CAREER Galois Representations Deformation Theory

项目摘要

For centuries, symmetry has played a central organizing role in the study of our mathematical and physical world. What may have begun as simple curiosity--for instance, the impulse to construct and classify the regular polyhedra nearly two and a half thousand years ago--has turned out time and again to be the most effective way to study some of the most fundamental objects of mathematics and physics, whether through the more concrete symmetries of geometrical objects or the more abstract (but essential to our digital world) symmetries of quantum mechanics. Perhaps the most surprising role of symmetry in the sciences is in the study of the prime numbers, the fundamental objects of arithmetic, where there are no manifest "symmetries" such as one encounters in geometry. Nevertheless, much of our deepest knowledge of prime numbers comes from their connections with the "symmetries" of polynomial equations, a subject known as Galois theory. This research project will study Galois representations, which are natural packages for algebraically encoding information about prime numbers. One of the central programs of modern number theory, proposes new ways to "unpack" Galois representations by relating them to remarkably different mathematical objects arising in geometry. The PI will continue his research in this direction to describe these mysterious but absolutely fundamental relationships. As part of the educational component of this CAREER project, the PI will undertake a series of educational projects serving a variety of audiences. He will continue to run an intensive summer number theory program for Utah high school students, introducing them to mathematics as an object of experimentation and discovery, and thereby encouraging them to develop the habits of mind essential to creative intellectual work. This program involves both graduate students and local high school teachers as co-teachers, who can then carry its distinctive pedagogical model with them to other educational settings. With a view toward exciting a broader mathematical public, the PI will also, in conjunction with teaching a history of mathematics course at The University of Utah, develop curricular materials, particularly videos, to be disseminated online, in the history of mathematics. Finally, he will continue his work training PhD students. In more detail, the Langlands program is a series of conjectures that guide much contemporary work in number theory, and in particular provide the deepest conjectural answers to problems relating Galois theory and prime numbers. In doing so, they reach out from number theory to algebraic geometry, representation theory, and beyond. The PI complete two main projects within the very broad purview of the Langlands program. The first concerns the deformation theory of Galois representations, one of the two pillars on which the proof of Fermat's Last Theorem was built, and ever since one of the central research areas within algebraic number theory. Here the PI will study the deformation theory of Galois representations valued in general reductive groups; broadly, this work aims at generalizations of Serre's famous modularity conjecture. The second main project concerns the relationship between Galois representations and motives, the latter being in some sense the best linear approximation to the category of algebraic varieties, of fundamental interest in its own right, but also conjecturally the algebro-geometric counterpart of Galois representations. Here the PI will study a variety of problems concerned with establishing the motivic origin of Galois representations. These include instances of the Fontaine-Mazur conjecture related to the PI's generalized Kuga-Satake theory; study of anabelian properties of moduli spaces; and motivic constructions underlying fundamental objects of geometric representation theory.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

几个世纪以来，对称性在我们的数学和物理世界的研究中发挥了重要的组织作用。什么可能已经开始作为简单的好奇心-例如，冲动建造和分类的正多面体近2500年前-已经一次又一次地被证明是最有效的方式来研究一些最基本的对象的数学和物理学，无论是通过几何对象的更具体的对称性，还是更抽象的对称性，（但对我们的数字世界至关重要）量子力学的对称性。也许对称性在科学中最令人惊讶的作用是在研究质数时，算术的基本对象，那里没有明显的“对称性”，如人们在几何中遇到的。尽管如此，我们对素数的最深层次的知识大多来自于它们与多项式方程的“对称性”的联系，这一主题被称为伽罗瓦理论。这个研究项目将研究伽罗瓦表示，这是自然的包代数编码信息的素数。现代数论的核心程序之一，提出了新的方法来“解包”伽罗瓦表示，将它们与几何中出现的显着不同的数学对象联系起来。PI将继续在这个方向上进行研究，以描述这些神秘但绝对基本的关系。作为该职业项目教育部分的一部分，PI将开展一系列为各种受众服务的教育项目。他将继续为犹他州的高中生开设一个密集的夏季数论课程，向他们介绍数学作为实验和发现的对象，从而鼓励他们培养创造性智力工作所必需的思维习惯。该计划涉及研究生和当地高中教师作为合作教师，然后他们可以将其独特的教学模式带到其他教育环境中。为了激发更广泛的数学公众，PI还将结合犹他州大学的数学史课程，开发课程材料，特别是视频，在数学史上在线传播。最后，他将继续他的工作，培养博士生。更详细地说，朗兰兹纲领是一系列指导许多当代数论工作的理论，特别是对伽罗瓦理论和素数相关问题提供了最深刻的理论答案。在这样做的过程中，他们从数论延伸到代数几何，表示论等。PI在朗兰兹计划的广泛范围内完成了两个主要项目。第一个涉及伽罗瓦表示的变形理论，费马大定理的证明建立在两个支柱之一，从此成为代数数论的中心研究领域之一。在这里PI将研究变形理论的伽罗瓦表示价值一般约化群;广泛地说，这项工作的目的是推广塞尔著名的模块性猜想。第二个主要项目涉及伽罗瓦表示和动机之间的关系，后者在某种意义上是代数簇范畴的最佳线性近似，其本身具有根本意义，但也是伽罗瓦表示的代数几何对应物。在这里，PI将研究与建立伽罗瓦表示的动机起源有关的各种问题。其中包括与PI的广义Kuga-Satake理论相关的Fontaine-Mazur猜想的实例;模空间的Anabelian性质的研究;以及几何表示理论基本对象的motivic构造。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估而被认为值得支持。
