Spherical functions associated with the three dimensional sphere
(2014)
In this paper, we determine all irreducible spherical functions of any K-type associated to the pair (G;K) = (SO(4); SO(3)). This is accomplished by associating to a vector valued function H = H(u) of a real variable ...
Curvature flows for almost-hermitian Lie groups
(2015)
We study curvature flows in the locally homogeneous case (e.g. compact quotients of Lie groups, solvmanifolds, nilmanifolds) in a unified way, by considering a generic flow under just a few natural conditions on the broad ...
Matrix Gegenbauer polynomials : the 2×2 fundamental cases
(2016)
In this paper, we exhibit explicitly a sequence of 2 × 2 matrix valued orthogonal polynomials
with respect to a weight W p,n , for any pair of real numbers p and n such that 0 < p < n. The entries of these polynomiales ...
Multimessenger search for sources of gravitational waves and high-energy neutrinos : results for initial LIGO-Virgo and IceCube
(2014-11-17)
We report the results of a multimessenger search for coincident signals from the LIGO and Virgo gravitational-wave observatories and the partially completed IceCube high-energy neutrino detector, including periods of joint ...
A performance evaluation of oscillation based test in continuous time filters
(2014)
This work evaluates the ability of OBT for detecting parametric faults in continuous-time filters. To this end, we adopt two filters with quite different topologies as cases of study and a previously reported statistical ...
Invariant solutions to the conformal Killing–Yano equation on Lie groups
(2015)
We search for invariant solutions of the conformal Killing–Yano equation on Lie groups equipped with left invariant Riemannian metrics, focusing on 2-forms. We show that when the Lie group is compact equipped with a ...
Co100-xFex magnetic thick films prepared by electrodeposition
(2015)
Co–Fe films are grown onto plane pre-treated Cu foils; the effects of the alloy composition on the morphology and the crystal texture of the electrodeposited films and their anisotropic magnetic hysteresis properties are ...
A pair production telescope for medium-energy gamma-ray polarimetry
(2014)
We describe the science motivation and development of a pair production telescope for medium-energy (∼5–200 MeV) gamma-ray polarimetry. Our instrument concept, the Advanced Energetic Pair Telescope (AdEPT), takes advantage ...
Center of mass and spin for isolated sources of gravitational radiation
(2016)
We define the center of mass and spin of an isolated system in general relativity. The resulting relationships between these variables and the total linear and angular momentum of the gravitational system are remarkably ...
Characterization, definability and separation via saturated models
(2014)
Three important results about the expressivity of a modal logic L are the Characterization Theorem (that identifies a modal logic L as a fragment of a better known logic), the Definability theorem (that provides conditions ...
