Regular triangulations of dynamic sets of points
The Delaunay triangulations of a set of points are a class of triangulations which play an important role in a variety of different disciplines of science. Regular triangulations are a generalization of Delaunay triangulations that maintain both their relationship with convex hulls and with Voronoi diagrams. In regular triangulations, a real value, its weight, is assigned to each point. In this...
متن کاملFixed Points of Asymptotically Regular Nonexpansive Mappings on Nonconvex Sets
It is shown that if X is a Banach space and C is a union of finitely many nonempty, pairwise disjoint, closed, and connected subsets {Ci : 1≤ i≤ n} of X , and each Ci has the fixed-point property (FPP) for asymptotically regular nonexpansive mappings, then any asymptotically regular nonexpansive self-mapping of C has a fixed point. We also generalize the Goebel-Schöneberg theorem to some Banach...
متن کاملUnitary t-designs
Unitary t-designs provide a method to simplify integrating polynomials of degree less than t over U(d). We prove a classic result the trace double sum inequality and use it to derive the fundamental symmetries of t-designs. As an alternate approach to deriving an asymptotically tight lower bound on the size of t-designs, we introduce a greedy algorithm for constructing designs. Unfortunately, w...
متن کاملUnitary designs and codes
A unitary design is a collection of unitary matrices that approximate the entire unitary group, much like a spherical design approximates the entire unit sphere. In this paper, we use irreducible representations of the unitary group to find a general lower bound on the size of a unitary t-design in U(d), for any d and t. We also introduce the notion of a unitary code — a subset of U(d) in which...
متن کاملImplementing Unitary 2-Designs Using Random Diagonal-unitary Matrices
Unitary 2-designs are random unitary matrices which, in contrast to their Haar-distributed counterparts, have been shown to be efficiently realized by quantum circuits. Most notably, unitary 2-designs are known to achieve decoupling, a fundamental primitive of paramount importance in quantum Shannon theory. Here we prove that unitary 2-designs can be implemented approximately using random diago...
