Time-reversal symmetry and random polynomials

D. Braun, M. Kus, K. Zyczkowski

We analyze the density of roots of random polynomials where each complex coefficient is constructed of a random modulus and a fixed, deterministic phase. The density of roots is sh…

Critical Adsorption in Systems with Weak Surface Field: The Renormalization-Group Approach

A. Ciach, U. Ritschel

We study the surface critical behavior of semi-infinite systems belonging to the bulk universality class of the Ising model. Special attention is paid to the local behavior of expe…

Hankel Multipliers And Transplantation Operators

Krzysztof Stempak, Walter Trebels

Connections between Hankel transforms of different order for $L^{p}$ -functions are examined. Well known are the results of Guy [Guy] and Schindler [Sch]. Further relations result fro…

Kernels of surjections from $L_{1}$ -spaces with an application to Sidon sets

Nigel J. Kalton, A. Pelczynski

If $Q$ is a surjection from $L^{1} (μ)$ , $μ$ $σ$ -finite, onto a Banach space containing $c_{0}$ then (*) $ker Q$ is uncomplemented in its second dual. If $Q$ is a surjection from an ${…

CPPA -- a New Hydrodynamical Code for Cosmological Large-Scale Structure Simulations

A. Kudlicki, T. Plewa, M. Rozyczka

We present a new Eulerian code able to follow the evolution of large-scale structures in the Universe in the weakly nonlinear regime. We compare test results with a N-body code and…

Unusual beats of the perpendicular-current giant magneto-resistance and thermopower of magnetic trilayers

S. Krompiewski, U. Krey

Oscillations of the giant magnetoresistance (GMR) and thermo-electric power (TEP) vs. both the thickness of the non-magnetic spacer and also that of the ferromagnetic slabs are stu…
