Quotientopes

Quotientopes For any lattice congruence of the weak order on Sn, N. Reading proved that glueing together the cones of the braid fan that belong to the same congruence class defines a complete fan.

Abstract

For any lattice congruence of the weak order on Sn, N. Reading proved that glueing together the cones of the braid fan that belong to the same congruence class defines a complete fan. We prove that this fan is the normal fan of a polytope.
