A Combinatorial Characterization of Sol 3-Manifolds
Daryl Cooper, Leslie Mavrakis, Priyam Patel
We show that there is a universal compact branched 3-manifold such that a closed 3-manifold immerses into if and only if admits a Sol structure. Equivalently, a clo…
Combinatorial Characterizations and Branched Manifolds
Daryl Cooper, Leslie Mavrakis, Priyam Patel
A family of compact n-manifolds is locally combinatorially defined (LCD) if it can be specified by a finite number of local triangulations. We show that LCD is equivalent to the ex…
Collar parameters for Teichmuller Space & Measured Foliations on a Surface Research Announcement
Daryl Cooper, Catherine Pfaff
We defined a new set of coordinates with respect to which the Thurston compactification of Teichmuller space is the radial compactification of Euclidean space.
The Thurston norm via spun-normal immersions
Daryl Cooper, Stephan Tillmann, William Worden
A theory of transversely oriented spun-normal immersed surfaces in ideally triangulated 3--manifolds is developed in this paper, including linear functionals determining the bounda…
On properly convex real-projective manifolds with Generalized Cusp
Daryl Cooper, Stephan Tillmann
Suppose is an end of an irreducible, properly convex, real-projective -manifold . If contains a subgroup of finite index isomorphic to , and $E\…
The space of properly-convex structures
Daryl Cooper, Stephan Tillmann
Suppose is finitely generated group and consists of all for which there exists a properly convex set in $\mathbb{R}\…
