On the Dec group of finite abelian Galois extensions over global fields
Jean B Nganou
If K/F is a finite abelian Galois extension of global fields whose Galois group has exponent t, we prove that there exists a short exact sequence that has as a consequence that if…
Angular Momentum Decomposition for an Electron
Matthias Burkardt, Hikmat BC
We calculate the orbital angular momentum of the `quark' in the scalar diquark model as well as that of the electron in QED (to order ). We compare the orbital angular momentum…
Justifications for Logic Programs under Answer Set Semantics
Enrico Pontelli, Tran Cao Son, Omar Elkhatib
The paper introduces the notion of off-line justification for Answer Set Programming (ASP). Justifications provide a graph-based explanation of the truth value of an atom w.r.t. a…
Spin-polarized high-energy scattering of charged leptons on nucleons
M. Burkardt, C. A. Miller, W. -D. Nowak
The proton is a composite object with spin one-half, understood to contain highly relativistic spin one-half quarks exchanging spin-one gluons, each possibly with significant orbit…
The Seventh Data Release of the Sloan Digital Sky Survey
K. Abazajian
This paper describes the Seventh Data Release of the Sloan Digital Sky Survey (SDSS), marking the completion of the original goals of the SDSS and the end of the phase known as SDS…
The Boer-Mulders Function: Models and Universality
Brian Hannafious, Matthias Burkardt
The sign of the Boer-Mulders function is related to the sign of the GPD through the mechanism of chromodynamic lensing. Model calculations of the sign of $\…
