Авторы: De Sanctis, Angela Аннотация: In the paper "Information Geometry of a regime-switching model with time-varying parameters" [1], we discussed the possibility to use tools derived from Information Geometry in order to analyze dynamical systems in which the motion randomly switches between two regimes using Markovian transitions. We proved that, in order to understand when an change can appear, the network properties of the system are important because they accelerate the diffusion of the information. In this note we recall the most important results obtained announcing some possible applications to detect the regime-switching in real phenomena. 2011-01-01T00:00:00Z https://elib.bsu.by:443/handle/123456789/13514 Заглавие документа: Internal Symmetry of a System of Three Dirac Fields. Авторы: Pletyukhov, V. A.; Strazhev, V. I.; Andrusevich, P. P. Аннотация: It is shown that the group SO(4,3) is the complete group of internal symmetry of the Lagrangian formulation of the theory of the Dirac fermion with three internal degrees of freedom. In the framework of relativistic quantum mechanics, the color symmetry group SU(3) can be considered as a maximal compact subgroup of the latter. 2011-01-01T00:00:00Z https://elib.bsu.by:443/handle/123456789/13513 Заглавие документа: Rashba Spin-Orbit Interaction in a Circular Quantum Ring in the Presence of a Magnetic Field. Авторы: Kudryashov, V. V.; Baran, A. V. Аннотация: Exact wave functions and energy levels are obtained for an electron in a two-dimensional semiconductor circular quantum ring with a confining potential of finite depth in the presence of both an external magnetic field and the Rashba spin-orbit interaction. 2011-01-01T00:00:00Z https://elib.bsu.by:443/handle/123456789/13512 Заглавие документа: Individual Human Capitals, Collective Behavior, and Age-Earnings Profiles of Workers: an Alternative Rationale and New Path to Modeling. Авторы: Maximov, Serguei Аннотация: In the article, an improved macro-level model is presented. The improvement concerns statistic averaging -- more reasonable distribution (Weibull) of individual "social" ages at intertemporal decision-making is used to get the macro-model. Simple (linear) regression based on the macro-model's specification is used to fit large samples (more than 40 age points) of empirical age-earnings data (UK, 2002; Canada, 1973, 1984, 1994). The found estimates of the pre-supposed "social" ages of persons to switch back and forth their educational efforts during life span are quite reasonable as well as the gender differences "detected" by the macro-model in such behavior. Findings presented in formulae, tables and graphs demonstrate the developed model's high accuracy in the regressions - better than in the Minceranian log-linear regressions. 2011-01-01T00:00:00Z
