Bregman Voronoi Diagrams
The Voronoi diagram of a point set is a fundamental geometric structure that partitions the space into elementary regions of influence defining a discrete proximity graph and dual...

A Revision of the Proof of the Kepler Conjecture
Abstract. The Kepler conjecture asserts that no packing of congruent balls in three-dimensional Euclidean space has density greater than that of the face-centered cubic packing. Th...

Optimal Angle Bounds for Quadrilateral Meshes
We show that any simple planar n-gon can be meshed in linear time by O(n) quadrilaterals with all new angles bounded between 60 and 120 degrees. 1991 Mathematics Subject Classifica...

Irreducible Apollonian Configurations and Packings
An Apollonian configuration of circles is a collection of circles in the plane with disjoint interiors such that the complement of the interiors of the circles consists of curvili...

Vertex Numbers of Weighted Faces in Poisson Hyperplane Mosaics
In the random mosaic generated by a stationary Poisson hyperplane process in Rd , we consider the typical k-face weighted by the j-dimensional volume of the j-skeleton (0 j k d)...

Star Unfolding Convex Polyhedra via Quasigeodesic Loops
We extend the notion of star unfolding to be based on a quasigeodesic loop Q rather than on a point. This gives a new general method to unfold the surface of any convex polyhedron ...

Conformal Mapping in Linear Time
Given any > 0 and any planar region bounded by a simple n-gon P we construct a (1 + )-quasiconformal map between and the unit disk in time C()n. One can take C() = C + C log ...
