Arc Permutations (extended abstract)

Authors: Elizalde, Sergi and Roichman, Yuval

Arc permutations and unimodal permutations were introduced in the study of triangulations and characters. In this paper we describe combinatorial properties of these permutations, including characterizations in terms of pattern avoidance, connections to Young tableaux, and an affine Weyl group action on them.
