Abstract:

In the framework of the method of phenomenological Lagrangians, we address the non-linear realizations of the Lie group G concerning the ’distortion’ of 12-dimensional space. Treating the ’distortion’ group G and its stationary subgroup H = SO(3), respectively, as the dynamical group and its algebraic subgroup, we identify the parameters of the quotient space G/H of adjacent classes by the subgroup H with the Goldstone fields of spontaneous breaking of ’distortion’ symmetry. We study the geometrical structure of the space of parameters in terms of Cartan forms introduced through the appropriate Maurer- Cartan’s structure equations. This allows us to infer the group invariants and calculate the conserved currents as its inevitable corollaries.

General note:

Communications of the Byurakan Astrophysical Observatory (ComBAO) is a peer-reviewed scientific journal, which publishes research in observational and theoretical astronomy/astrophysics and presents recent advances in these fields. It is being published by the NAS RA V. Ambartsumian Byurakan Astrophysical Observatory (BAO) in English in electronic form. The journal publishes original papers, review papers, brief reports, book reviews, special communications, observational and theoretical results in various fields of astronomy and related sciences, and some editorial notes, including anniversaries and obituaries. Under the heading “Legacy”, the renewed magazine will republish some old articles of high value in English. The heading “Guest articles” will bring to the attention of readers the articles of researchers who are not employees of BAO. ComBAO was founded in 1946 and regularly published in 1946-1990. However, the publication was interrupted because of the economic situation after the disintegration of the Soviet Union in 1991.
