Abstract:
Partial permutohedra are lattice polytopes which were recently introduced and studied by Heuer and Striker. For positive integers m and n, the partial permutohedron~\cP(m,n) is the convex hull of all vectors in {0,1,…,n}m with distinct nonzero entries. In this talk I will present results on the face lattice, volume and Ehrhart polynomial of \cP(m,n). This is joint work with Behrend, Castillo, Chavez, Diaz-Lopez, Harris and Insko.
