2011 8th International Symposium on Wireless Communication Systems, Aachen New Achievable Rates for the Gaussian Broadcast Channel with Feedback

by Michael Gastpar, Amos Lapidoth, Yossef Steinberg, Michèle Wigger
"... Abstract—A coding scheme for the two-receivers Gaussian broadcast channel (BC) with feedback is proposed. For some asymmetric settings it achieves new rate pairs. Moreover, it achieves prelog 2 when the noises at the two receivers are fully positively correlated and of unequal variances, thus allowi ..."

1 Dedicated to Ludwig Elsner on the occasion of his sixtieth birthday We describe canonical forms for elements of a classical Lie group of matrices under similarity transformations in the group. Matrices in the associated Lie algebra and Jordan algebra of matrices inherit related forms under these similarity transforma-tions. In general, one cannot achieve diagonal or Schur form, but the form that can be achieved displays the eigenvalues of the matrix. We also discuss matrices in in-tersections of these classes and their Schur-like forms. Such multistructered matrices arise in applications from quantum physics and quantum chemistry. 1

"... Abstract. We give a new proof of regularity of biharmonic maps from four-dimensional domains into spheres, showing first that the biharmonic map system is equivalent to a set of bilinear identities in divergence form. The method of reverse Hölder inequalities is used next to prove continuity of sol ..."

An Infinite Set of Ward Identities for Adiabatic Modes in Cosmology

by Kurt Hinterbichlera, Lam Huib, Justin Khouryc
"... We show that the correlation functions of any single-field cosmological model with constant growing-modes are constrained by an infinite number of novel consistency relations, which relate N + 1-point correlation functions with a soft-momentum scalar or tensor mode to a symmetry transformation on N- ..."

constrain — completely for n = 0, 1, and partially for n ≥ 2 — the qn behavior of the soft limits. The identities at n = 0 recover Maldacena’s original consistency relations for a soft scalar and tensor mode, n = 1 gives the recently-discovered conformal consistency relations, and the identities for n ≥ 2
