Dynamical invariants and manipulation of electron spin in a quantum dot
In this paper we discuss electrical manipulation of a spin an electron in quantum dot within a weak magnetic field. Approach to describing this process is based on Lewis — Riesenfeld dynamical invariants. Necessary conditions of a spin-flip process are derived.

Portfolio optimization in the case of an exponential utility function and in the presence of an illiquid asset
... and we obtain essentially different results. We provide the Lie group analysis of the corresponding HJB equation.
For the main three-dimensional PDE with the exponential utility function, we obtain the complete set of the nonequivalent Lie group invariant reductions to two-dimensional PDEs according to an optimal system of subalgebras of the admitted Lie algebra. We prove that in just one case the invariant reduction is consistent with the boundary condition. This reduction represents a significant ...

... “Delirium” collection (1993) and establishes the equality of semantics between giving/gift and parting, breaking apart, which allows to bring the concept of “giving/ gift” to the core of the poet’s concept structure. The article defines a semantic invariant and studies the ways of its invariant development, analyzes connection between the relevant concepts and categories of space and movement, life and death. The semantic reconstruction is performed through play Multilanguage anagram code, which ...
Communicative semantics theories by A. F. Losev and Z. A. Vardzelashvili
The article deals with a comparative analysis of the foundations of the theory of invariant communicative interpretive semantics by the Russian scholar A. F. Losev and the semantic concept developed by Z. A. Vardzelashvili, professor of Tbilisi State University of Economics.
