Representing the Sporadic Archimedean Polyhedra as Abstract Polytopes
Michael Hartley, Gordon Williams
We present the results of an investigation into the representations of Archimedean polyhedra (those polyhedra containing only one type of vertex figure) as quotients of regular abs…
A concise proof of Kruskal's theorem on tensor decomposition
John A. Rhodes
A theorem of J. Kruskal from 1977, motivated by a latent-class statistical model, established that under certain explicit conditions the expression of a 3-dimensional tensor as the…
Streamers, sprites, leaders, lightning: from micro- to macroscales
Ute Ebert, Davis D. Sentman
"Streamers, sprites, leaders, lightning: from micro- to macroscales" was the theme of a workshop in October 2007 in Leiden, The Netherlands; it brought researchers from plasma phys…
Identifiability of parameters in latent structure models with many observed variables
Elizabeth S. Allman, Catherine Matias, John A. Rhodes
While hidden class models of various types arise in many statistical applications, it is often difficult to establish the identifiability of their parameters. Focusing on models in…
A class of solutions of the vacuum Einstein constraint equations with freely specified mean curvature
David Maxwell
We give a sufficient condition, with no restrictions on the mean curvature, under which the conformal method can be used to generate solutions of the vacuum Einstein constraint equ…
The Identifiability of Covarion Models in Phylogenetics
Elizabeth S. Allman, John A. Rhodes
Covarion models of character evolution describe inhomogeneities in substitution processes through time. In phylogenetics, such models are used to describe changing functional const…
