Benefits to the U.S. from Physicists Working at Accelerators Overseas
Jacob Anderson, Raymond Brock, Yuri Gershtein +12
We illustrate benefits to the U.S. economy and technological infrastructure of U.S. participation in accelerators overseas. We discuss contributions to experimental hardware and an…
Introducing Totally Nonparallel Immersions
Michael Harrison
An immersion of a smooth -dimensional manifold is called totally nonparallel if, for every distinct , the tangent spaces at and co…
Algorithms for Del Pezzo Surfaces of Degree 5 (Construction, Parametrization)
Jon Gonzalez-Sanchez, Michael Harrison, Irene Polo-Blanco +1
It is well known that every Del Pezzo surface of degree 5 defined over k is parametrizable over k. In this paper we give an efficient construction for parametrizing, as well as alg…
Two robots moving geodesically on a tree
Donald M. Davis, Michael Harrison, David Recio-Mitter
We study the geodesic complexity of the ordered and unordered configuration spaces of graphs in both the and metrics. We determine the geodesic complexity of the…
Skew and sphere fibrations
Michael Harrison
A great sphere fibration is a sphere bundle with total space and fibers which are great -spheres. Given a smooth great sphere fibration, the central projection to any tang…
SIC-POVMs from Stark units: Prime dimensions n^2+3
Marcus Appleby, Ingemar Bengtsson, Markus Grassl +2
We propose a recipe for constructing a SIC fiducial vector in complex Hilbert space of dimension of the form , focussing on prime dimensions . Such structures are sho…
