On the dimensions of correlated equilibrium polytopes of generic games
Jan Draisma, Linda Hoyer, Irem Portakal
In this paper, we study the dimension of the correlated equilibrium polytope of finite games. Under the oriented-matroid notion of genericity, we prove that if a generic game is no…

The space of preorders on a commutative monoid
Jan Draisma, George Metcalfe, Simon Santschi
For a finitely generated commutative monoid , we present a constructive description of all (total) preorders on that are compatible with the monoid structure. Equipped wit…

Sym-Noetherianity for powers of GL-varieties
Christopher H. Chiu, Alessandro Danelon, Jan Draisma +2
Much recent literature concerns finiteness properties of infinite-dimensional algebraic varieties equipped with an action of the infinite symmetric group, or of the infinite genera…
