Title: The flags of Minkowski sums of simplices
Abstract: An interesting class of polytopes that includes various known types of polytopes like hyper-simplices, permutahedra, associahedra and even some matriod base polytopes is formed by the Minkowski sums of simplices in R^n of fixed dimension. These polytopes can further be viewed as a certain building blocks for certain generalized permutahedra. In this talk we discuss the flags of these Minkowski sums and some of their face lattice structure
