Raman Sanyal, Frank Sottile, Bernd Sturmfels
An orbitope is the convex hull of an orbit of a compact group acting linearly on a vector space. These highly symmetric convex bodies lie at the crossroads of several fields, in pa…

Non-projectability of polytope skeleta
Thilo Rörig, Raman Sanyal
We investigate necessary conditions for the existence of projections of polytopes that preserve full k-skeleta. More precisely, given the combinatorics of a polytope and the dimens…

Ehrhart theory, Modular flow reciprocity, and the Tutte polynomial
Felix Breuer, Raman Sanyal
Given an oriented graph G, the modular flow polynomial counts the number of nowhere-zero Z_k-flows of G. We give a description of the modular flow polynomial in terms of (open) Ehr…
