Dependence on parameters for discrete second order boundary value problems
Marek Galewski
We investigate the dependence on parameters for second order difference equations with two point boundary value conditions by using a variational method in case when the correspond…
The background from single electromagnetic subcascades for a stereo system of air Cherenkov telescopes
Dorota Sobczynska
The MAGIC experiment, a very large Imaging Air Cherenkov Telescope (IACT) with sensitivity to low energy (E < 100 GeV) VHE gamma rays, has been operated since 2004. It has been fou…
The eigenvectors of semigroups of positive maps on von Neumann algebras
Andrzej Łuczak
The eigenvectors of an ergodic semigroup of linear normal positive unital maps on a von Neumann algebra are described. Moreover, it is shown by means of examples, that mere positiv…
Three steps to accelerated expansion
Orest Hrycyna, Marek Szydlowski
We study the dynamics of a non-minimally coupled scalar field cosmology with a potential function. We use the framework of dynamical systems theory to investigate all evolutional p…
Simultaneous multi-frequency observation of the unknown redshift blazar PG 1553+113 in March-April 2008
MAGIC Collaboration, J. Aleksić, H. Anderhub +161
The blazar PG 1553+113 is a well known TeV gamma-ray emitter. In this paper, we determine its spectral energy distribution using simultaneous multi-frequency data in order to study…
Quantum Preferred Frame: Does It Really Exist?
J. Rembielinski, K. A. Smolinski
The idea of the preferred frame as a remedy for difficulties of the relativistic quantum mechanics in description of the non-local quantum phenomena was undertaken by such physicis…
