On the Equivalence of the General Covariance Union (GCU) and Minimum Enclosing Ellipsoid (MEE) Problems
Ottmar Bochardt, Jeffrey Uhlmann
In this paper we describe General Covariance Union (GCU) and show that solutions to GCU and the Minimum Enclosing Ellipsoid (MEE) problems are equivalent. This is a surprising resu…
Vertical versus conical square functions
Pascal Auscher, Steve Hofmann, José Maria Martell
We study the difference between vertical and conical square functions in the abstract and also in the specific case where the square functions come from an elliptic operator.
Spin Drag in Ultracold Fermi Mixtures with Repulsive Interactions
R. A. Duine, Marco Polini, Arnaud Raoux +2
We calculate the spin-drag relaxation rate for a two-component ultracold atomic Fermi gas with positive scattering length between the two spin components. In one dimension we find…
Non-orthogonal fusion frames and the sparsity of fusion frame operators
Jameson Cahill, Peter Casazza, Shidong Li
Fusion frames have become a major tool in the implementation of distributed systems. The effectiveness of fusion frame applications in distributed systems is reflected in the effic…
An Extension of the IAU Framework for Reference Systems
Sergei Kopeikin
IAU 2000 resolutions on the reference frames set up a solid theoretical foundation for implementing general relativity in astronomical data processing algorithms and for unambiguou…
Electronic Phases and Phase Separation in the Hubbard-Holstein Model of a Polar Interface
B. R. K Nanda, S. Satpathy
From a mean-field solution of the Hubbard-Holstein model, we show that a rich variety of different electronic phases can result at the interface between two polar materials such as…
