On degree sequences of undirected, directed, and bidirected graphs
Laura Gellert, Raman Sanyal
Bidirected graphs generalize directed and undirected graphs in that edges are oriented locally at every node. The natural notion of the degree of a node that takes into account (lo…

Combinatorial positivity of translation-invariant valuations and a discrete Hadwiger theorem
Katharina Jochemko, Raman Sanyal
We introduce the notion of combinatorial positivity of translation-invariant valuations on convex polytopes that extends the nonnegativity of Ehrhart h*-vectors. We give a surprisi…
