Decomposing Centrally Symmetric Convex Polyhedral Surfaces into Parallelograms

Zili Wang, Cong Wu

Let $M_{2 N} (δ_{1}, δ_{2}, \dots, δ_{N})$ be the moduli space of centrally symmetric convex polyhedral surfaces with $2 N$ labeled vertices and prescribed cone-deficits $δ_{1}$ , $δ_…

Taut fillings

Peter Doyle, Matthew Ellison, Zili Wang

Let $σ$ be a simplicial triangulation of the 2-sphere, $X$ the associated integral 2-cycle. A filling of $X$ is an integral 3-chain $M$ with $\partial M = X$ ; a taut filling is one…

Flip Distance and Triangulations of a Ball

Zili Wang

It is known that the flip distance between two triangulations of a convex polygon is related to the minimum number of tetrahedra in the triangulation of some polyhedron. It is inte…

Strong convexity in flip-graphs

Lionel Pournin, Zili Wang

The set of triangulations of a surface $Σ$ with a prescribed set $X$ of vertices can be endowed with a graph structure $F (Σ, X)$ called a flip-graph, whose edges connect t…

Shapes of Centrally Symmetric Octahedra with Prescribed Cone-Deficits

Zili Wang

In his paper "Shapes of Polyhedra and Triangulations of the Sphere", Thurston found that the set of shapes of convex polyhedra with prescribed cone-deficits has a complex hyperboli…
