DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Matroids/21/
 ">Partial Permutohedra</a>\nby Laura Escobar Vega (Washington University i
 n St. Louis) as part of Matroids - Combinatorics\, Algebra and Geometry Se
 minar\n\nLecture held in Room 210 The Fields Institute.\n\nAbstract\nParti
 al permutohedra are lattice polytopes which were recently introduced\nand 
 studied by Heuer and Striker. For positive integers $m$ and $n$\, the part
 ial permutohedron~$\\cP(m\,n)$ is the convex hull of all vectors in $\\{0\
 ,1\,\\ldots\,n\\}^m$ with distinct nonzero entries. In this talk I will pr
 esent 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.\n
