The Range of United K-Theory
Jeffrey L. Boersema
We prove that united K-theory is a surjective functor from the category of real simple purely infinite C*-algebras to the cateogry of countable acyclic CRT-modules.
Complexes of graph homomorphisms
Eric Babson, Dmitry N. Kozlov
is a polyhedral complex defined for any two undirected graphs and . This construction was introduced by Lovász to give lower bounds for chromatic numbers of graph…
Isomorphism rigidity in entropy rank two
Manfred Einsiedler, Thomas Ward
We study the rigidity properties of a class of algebraic Z^3-actions with entropy rank two. For this class, conditions are found which force an invariant measure to be the Haar mea…
On nonuniqueness for Calderon's inverse problem
Allan Greenleaf, Matti Lassas, Gunther Uhlmann
We construct anisotropic conductivities with the same Dirichlet-to-Neumann map as a homogeneous isotropic conductivity. These conductivities are singular close to a surface inside…
Relativity, chiral symmetry, and the nucleon electromagnetic form factors
Gerald A. Miller
A relativistic interpretation for why the proton's falls and is approximately constant is presented. Reproducing the observed mandates the inclusion of…
