Stabilization of Tsirelson-type norms on spaces
Anna Maria Pelczar
We consider classical Tsirelson-type norms of and their modified versions on spaces. We show that for any there is a constant such that consi…
Non-integrability of density perturbations in the FRW universe
Tomasz Stachowiak, Marek Szydlowski, Andrzej J. Maciejewski
We investigate the evolution equation of linear density perturbations in the Friedmann-Robertson-Walker universe with matter, radiation and the cosmological constant. The concept o…
Images of a Bose-Einstein condensate at finite temperature
Jacek Dziarmaga
A condensate initially prepared at finite temperature evolves under external time-dependent perturbation into a time-dependent mixed state. In these notes I use number-conserving t…
Expected term bases for generic multivariate Hermite interpolation
Marcin Dumnicki
The main goal of the paper is to find an effective estimation for the minimal number of generic points in for which the basis for Hermite interpolation consists of th…
Population explosion suppressed by noise: Stationary distributions and how to simulate them
P. F. Gora
We show that two dynamical systems exhibiting very different deterministic behaviours possess very similar stationary distributions when stabilized by a multiplicative Gaussian whi…
