Conjectures for Cutting Pizza with Coxeter Arrangements

Research output: Contribution to journalArticlepeer-review

Abstract

We are interested in conjecturing the sign of the pizza quantity (Formula presented.) for the irreducible Coxeter arrangements (Formula presented.) of type An, where (Formula presented.) or (Formula presented.), and type Dn, where n is odd. Our approach is to express the pizza quantity in terms of the pizza quantity of subarrangements known as 2-structures, and we obtain the first non-zero term in the multivariate Taylor expansion.
