Anisotropic flow fluctuations in hydro-inspired freeze-out model for relativistic heavy ion collisions

The LHC data on event-by-event harmonic flow coefficients measured in PbPb collisions at center-of-mass energy 2.76 TeV per nucleon pair are analyzed and interpreted within the HYDJET++ model. To compare the model results with the experimental data the unfolding procedure is employed. The essentially dynamical origin of the flow fluctuations in hydro-inspired freeze-out approach has been established. It is shown that the simple modification of the model via introducing the distribution over spatial anisotropy parameters permits HYDJET++ to reproduce both elliptic and triangular flow fluctuations and related to it eccentricity fluctuations of the initial state at the LHC energy.Comment: 12 pages including 9 figures as EPS-files; prepared using LaTeX package for publication in the European Physical Journal

Torsion free groups with indecomposable holonomy group I

We study the torsion free generalized crystallographic groups with the indecomposable holonomy group which is isomorphic to either a cyclic group of order ${p^s}$ or a direct product of two cyclic groups of order ${p}$.Comment: 22 pages, AMS-Te

Radicalism and Reformism in Political Controversy Tories in Great Britain in First Third of 19th Century

A radical and reformist discourse on the nature and limits of the “folk element” in the British political system in the first third of the 19th century is considered. The key features of this discourse and the role it played in shaping a broad Tory identity are studied. It is shown that during the period under study, the focus of political controversy shifted from issues of sovereignty and royal prerogative to issues related to fair popular representation and the nature of the necessary political reforms. The novelty of the study lies in the emphasis on the fact that it was the abuse of power by the “popular element” in the British constitutional system that was the main threat to sustainable development. This thesis is supported by documentary evidence, including those first introduced into scientific circulation. It is emphasized that the broad Tory identity that developed during the period under study was based on adherence to the ideals of the constitutional order, established as a result of the Glorious Revolution. The author’s assessment of how the various approaches of the Tory groups to the issue of reform eroded the broad identity of the Tories, creating a basis for the formation of political ideas of conservatism, is presented
