The method of closed chains of discrete symmetries is used to multiply Toda lattices in one and two spatial dimensions. Using the modified Toda equations m0TCand m1TC as an example, it is shown that the combination of the Darboux and Schlesinger transformations leads to closed dressing chains. 1. Matveev V.

There is a quantum statistical model of prototropic tautomeic transformation caused by vertical transition between different adiabatic potentials with two minima divided by potential barrier offered. Formula for the probability function defining time of tautomer transformation without regard to vibronic relaxation ...

It is considered a possibility of generation of exact solutions for Friedman equations by Darboux transformation, for which Cardy — Verlinde formula is valid. Two modifications of Darboux transformation are offered, which let generate such solutions. Exact solutions are obtained, for which Cardy — Verlinde formula is valid at least near some singularities....

This research focuses on the features and transformations of power groups and their role in the political life of the societies of the Baltic countries. This article aims to analyse structural and functional changes in the composition of the Baltic political elites after these countries gained ...

... regional development processes in the East of the Baltic Sea. The research aims to verify the theory of peripheral capitalism as applied to the Baltic States. The first theoretical objective is to draw a distinction between the ideas of modernisation and transformation in a regional context. The second objective is to adjust the theory of peripheral capitalism to smaller states. To study the features of the transformation of economic and political systems in the Baltics, this article conducts comparative ...

... that information and analytical technology for modeling dragline waste rehandling in three-dimensional space through two-dimensional numerical algorithms. Using the methods of analytical geometry and mathematical statistics, a number of problems of transforming basic data to net models, creating average sections and local systems of coordinates, modeling routes of excavators in local systems of coor-dinates, and return transformation of modeling results to the initial system of coordinates have ...

This article offers the results of an analysis of natural and anthropogenic impacts on eolian coastal marine natural complexes of the Curonian and Vistula spits. The authors identify the contribution of natural and anthropogenic factors to the transformation of the spits’ natural complexes. 1. Бадюкова Е. Н., Жиндарев Л. А., Лукьянова С. А. и др.

We study discrete isospectral symmetries for the linear problem in spatial dimensions two, by developing a Darboux (Moutard) transformation formalism for this problem. As an application, we construct some singular and nonsingular integrable potentials (dielectric permitivity) for the Maxwell equations in a 2D inhomogeneous medium. 1. Yurova A. A., Yurov A. V., Rudnev M. Darboux ...

A quantum statistical model of intramolecular tautomeric transformation is offered, accounts for the vibration of a proton as a result of its interaction with the surrounding medium simulated by the quantized field of radiation. Effective adiabatic potentials of the proton are approximated by the parabolas ...

... disintegration and further development of the country's policy. The role of the political elite, which is understood according to R. Putnam and J. Higley's definition, is considered in the conditions of political instability and uncertainty typical of transformation processes. In this context, the role of key actors is interpreted on the basis of the methodological structure of the so-called Stanford model developed by G. Almond and P. Bourdieu's theory of capital. This article reconstructs the course ...

The article examines the scope and significance of semantic transformations of the secondary text — the fairy tale Der Ritter Blaubart” by Alfred Döblin. The article reveals that the transformation of the tale, which emerged in the stream of post-modernism, is a complex formation which reveals both the features ...

The aim of the study is to define the role of organized crime in Russia over a major period in the 20th century, and analyze transformation that this criminal activity underwent. The article opens with the analysis of the development processes of the organized crime typical for the Soviet society. It is shown that in the Soviet period of history, organized crime, inheriting ...

... from February 2019 to January 2021. The findings suggest that Russian regions may be divided into digitally advanced areas, runner-ups, average performers, and the digital periphery. Recommendations are given on how to increase readiness for digital transformation in territories of different types without running the risks of forced digitalisation. 1. Plotichkina, N.

... as a complete and organized formation in the structure of a film work that has clearly defined functions. Contrastive approach allows to consider the adapted film dialogue in comparison with its original literary dialogue and to identify a number of transformations that take place in the process of its adaptation for a film. Undertaken linguistic analysis can serve as the basis for further study of the actual language material in the context of film adaptation as a linguistic problem. 1. Горшкова ...

The authors study the issue of acausal semantic coincidences (synchro­nicity) for the first time as omens of war in the Russian linguocultural tradi­tion. The semiotic structure of omens is shown, and models of transformations of situational semantics in their signifier and signified are revealed. In partic­ular, symbolic substitutions are possible in the signifier, and a sequence of metonymic shifts in the causal field of war in the signified. In general, ...
