On dual unit balls of Thurston norms
Published online by Cambridge University Press: 07 October 2021
Abstract
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 
$\mathbb {R}^{2g}$
that appear like dual unit balls of Thurston norms, generalizing Thurston’s construction for polygons in 
$\mathbb {R}^2$
.
