This research program seeks to understand quantum field theory using a combinatorial aesthetic and toolbox and to develop new combinatorial and physical tools that lead to new insights. The program provides new approaches for understanding Feynman integrals and how they are put together into series which calculate physical observables. Consequently it has the potential to lead to significant advances in how we understand the building blocks which make up our world. The work of the program centers on two main foci: the graph theory of Feynman periods and the recursive combinatorics of Dyson-Schwinger equations.

该研究计划旨在使用组合美学和工具箱来理解量子场论，并开发新的组合和物理工具，以获得新的见解。该程序提供了新的方法来理解费曼积分，以及如何将它们放在一起，计算物理可观的一系列。 因此，它有可能导致我们在如何理解构成我们世界的基石方面取得重大进展。 该程序的工作集中在两个主要焦点：费曼周期的图论和戴森-施温格方程的递归组合。
