Basics of M-Theory
A. Miemiec, I. Schnakenburg
This is a review article of eleven dimensional supergravity in which we present all necessary calculations, namely the Noether procedure, the equations of motion (without neglectin…
The Scaling of QED in a Non-Commutative Space-Time
J. Volkholz, W. Bietenholz, J. Nishimura +1
We present results of numerical simulations for pure U(1) gauge theory in a non-commutative space. The theory is mapped onto a dimensionally reduced matrix model, which renders its…
Monte-Carlo simulation of the chiral Gross-Neveu model
Tomasz Korzec, Francesco Knechtli, Ulli Wolff +1
We investigate the two flavor chiral Gross-Neveu model in the Schroedinger functional on the lattice. The procedure necessary to recover chiral symmetry in the continuum limit of t…
Nearly Kaehler and nearly parallel G_2-structures on spheres
Thomas Friedrich
In some other context, the question was raised how many nearly Kähler structures exist on the sphere equipped with the standard Riemannian metric. In this short note, we prov…
Schrödinger operator with a junction of two 1-dimensional periodic potentials
Evgeny Korotyaev
The spectral properties of the Schrödinger operator in are studied, with a potential and where ar…
Observations of Selected AGN with H.E.S.S
F. Aharonian et al.
A sample of selected active galactic nuclei (AGN) was observed in 2003 and 2004 with the High Energy Stereoscopic System (H.E.S.S.), an array of imaging atmospheric-Cherenkov teles…
