Holographic Chern-Simons Theories

, 2014
Chern-Simons theories in three dimensions are topological field theories that may have a holographic interpretation for suitable chosen gauge groups and boundary conditions on the fields.

Quasi-plane waves for a particle with spin 1/2 on the background of Lobachevsky geometry: simulating of a special medium

, 2012
In the paper complete systems of exact solutions for Dirac and Weyl equations in the Lobachevsky space are constructed on the base of the method of separation of the variables in quasi-cartesian coordinates.

On Elliptical Billiards in the Lobachevsky Space and associated Geodesic Hierarchies

, 2002
We derive Cayley's type conditions for periodical trajectories for the billiard within an ellipsoid in the Lobachevsky space. It appears that these new conditions are of the same form as those obtained before for the Euclidean case.

The geometrical sizes on Lobachevski plane

Pracì Mìžnarodnogo Geometričnogo Centru, 2015
In this paper we investigate a local structure of geometrical quantities on the Lobachevski plane. This structure is used to describe metric differential invariants on the Lobachevski plane ([1]).

Nonrelativistic approximation for quasi-planes waves of a spin 1 particle in Lobachevsky space

, 2012
Spin 1 particle in Pauli approximation is investigated on the background of the curved space of constant negative curvature, Lobachevsky space. Nonrelativistic approximation is performed in the system of 10 equations resulted from separating the variables in Duffin-Kemmer equation specified in quasi-cartesian coordinates.

Hyperbolic geometry in the work of Johann Heinrich Lambert

, 2014
The memoir Theorie der Parallellinien (1766) by Johann Heinrich Lambert is one of the founding texts of hyperbolic geometry, even though its author's aim was, like many of his pre-decessors', to prove that such a geometry does not exist. In fact, Lambert
