项目摘要

This project will establish a new framework that connects the physics of certain two-dimensional physical systems, called conformal field theories (CFTs), with the mathematics of certain well-studied algebraic objects, called quantum groups. Establishing such a connection will greatly advance our understanding of both subjects, and provide novel tools for studying two-dimensional CFTs. In implementing this project, new research opportunities will be created for undergraduates and early graduate students. These research opportunities will be supported by grant funding. The PI will also provide direct support for preexisting programs which seek to increase access to mathematics among women and underrepresented minorities.In more detail, one component of the project is to find an equivalence of (ribbon tensor) categories between the representation category of the so-called triplet vertex algebra, and the representation category of small quantum SL(2). Such an equivalence was conjectured by mathematical physicists in the mid-2000’s, and some explicit progress has been made towards its resolution in recent works of the PI and others. A positive resolution to this conjecture will provide the first direct link between logarithmic CFTs and quantum groups, a phenomenon which should be endemic among the most fundamental classes of logarithmic CFTs. A second component of the project is the computation of the Balmer spectrum for small quantum groups associated to arbitrary simple algebraic groups. This computation will employ and establish new links between support theory and 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.

该项目将建立一个新的框架，将某些二维物理系统的物理学（称为共形场论（CFTs））与某些经过充分研究的代数对象（称为量子群）的数学联系起来。建立这样的联系将大大促进我们对这两个主题的理解，并为研究二维CFTs提供新的工具。在实施这一项目时，将为本科生和早期研究生创造新的研究机会。这些研究机会将得到赠款资金的支持。PI还将直接支持旨在增加妇女和代表性不足的少数民族对数学的接触的现有计划。更详细地说，该项目的一个组成部分是找到所谓的三重顶点代数的表示类别与小量子SL（2）的表示类别之间的（带状张量）类别的等价性。这种等价性在2000年代中期被数学物理学家证明，在PI和其他人最近的工作中，已经取得了一些明确的进展。这个猜想的一个积极的解决方案将提供对数CFTs和量子群之间的第一个直接联系，这种现象应该是最基本的对数CFTs类中的地方病。该项目的第二个组成部分是计算与任意简单代数群相关的小量子群的巴耳末谱。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，被认为值得支持。
