Stallings introduced the concept of Stallings to aid in the study of free groups, which creates a "folded graph" associated with a subgroup of a free group. Dani-Levcovitz adapted this concept to the setting of Right-Angled Coxeter Groups. In this talk, we will introduce Coxeter Groups and folded graphs, and demonstrate how to use these graphs to compute intersections of subgroups of Coxeter groups.
