Recent advances in representation theory have revealed beautiful new structures in the classical representation theory of the symmetric groups and Hecke algebras. These discoveries have provided us with new algebras, the cyclotomic KLR algebras, that encode deep properties of fundamental objects in algebraic combinatorics and geometric representation theory. The cyclotomic quiver Hecke algebras are central to several open problems in mathematics but they are still poorly understood, with even basic properties like their dimensions being unknown. This project will establish a new framework for studying these algebras that will remove the current obstacles in this field and alllow us to prove substantial new results that advance the theory.

表示论的最新进展揭示了对称群和Hecke代数的经典表示论中美丽的新结构。这些发现为我们提供了新的代数，分圆KLR代数，编码代数组合学和几何表示理论中的基本对象的深层属性。分圆Hecke代数是数学中几个开放问题的核心，但它们仍然知之甚少，甚至连它们的维数等基本性质都是未知的。这个项目将建立一个新的框架来研究这些代数，这将消除目前在这一领域的障碍，并允许我们证明实质性的新结果，推进理论。
