On dual unit balls of Thurston norms
Résumé
Thurston norms are invariants of 3-manifolds defined on their second homology and understanding the shape of their dual unit balls is a widely open problem. In this article, we provide a large family of polytopes in R^2g that appear like dual unit balls of Thurston norms, generalizing Thurston's construction for polygons in R^2.
