Geometric aspects of the Maximum Principle and lifts over a bundle map

B. Langerock

A coordinate-free proof of the Maximum Principle is provided in the specific case of an optimal control problem with fixed time. Our treatment heavily relies on a special notion of…

Three-component Stackel potentials satisfying recent estimates of Milky Way parameters

B. Famaey, H. Dejonghe

We present a set of three-component Stackel potentials defined by five parameters and designed to model the Milky Way. We review the fundamental constraints that any model of the M…

Measurement of single-spin azimuthal asymmetries in semi-inclusive electroproduction of pions and kaons on a longitudinally polarised deuterium target

HERMES collaboration, A. Airapetian

Single-spin asymmetries have been measured for semi-inclusive electroproduction of , , and mesons in deep-inelastic scattering off a longitudinally polarised…

Purely gravito-magnetic vacuum space-times

N. Van den Bergh

It is shown that there are no vacuum space-times (with or without cosmological constant) for which the Weyl-tensor is purely gravito-magnetic with respect to a normal and timelike…

On the SL(2,R) symmetry in Yang-Mills Theories in the Landau, Curci-Ferrari and Maximal Abelian Gauge

D. Dudal, V. E. R. Lemes, M. Picariello +3

The existence of a SL(2,R) symmetry is discussed in SU(N) Yang-Mills in the maximal Abelian Gauge. This symmetry, also present in the Landau and Curci-Ferrari gauge, ensures the ab…

Erratum to: "Nuclear Effects on R=σ_L/σ_T in Deep-Inelastic Scattering" Phys.Lett. B475(2000)386

HERMES Collaboration, A. Airapetian

This erratum revokes the main conclusion of a Letter that reported measurements of cross sections for deep-inelastic scattering (DIS) of leptons on He and N targets, exp…
