Parity Violation and Arrow of Time in Generalized Quantum Dynamics
Vadim V. Asadov, Oleg V. Kechkin
It is shown, that parity violation in quantum systems can be a natural result of their dynamical evolution. The corresponding (completely integrable) formalism is based on the use…
Heterotic string theory interrelations
Oleg V. Kechkin
We establish a symmetry map which relates two low-energy heterotic string theories with different numbers of the Abelian gauge fields compactified from the diverse to three dimensi…
New matrix formalism for heterotic string theory on a torus
Oleg V. Kechkin
A new Lagrange formalism based on the use of a single scalar (d+1)X(d+1+n) matrix potential is developed for the low-energy heterotic string theory with n U(1) gauge fields compact…
O(d, d)-Symmetry and Ernst Formulation for Einstein-Kalb-Ramond Theory in Two Dimensions
A. Herrera, O. Kechkin
The (3+d)-dimensional Einstein-Kalb-Ramond theory reduced to two dimensions is considered. It is shown that the theory allows two different Ernst-like matrix formulati…
O(d, d)-Symmetry and Ernst Formulation for Einstein-Kalb-Ramond Theory in Three Dimensions
A. Herrera, O. Kechkin
The Ernst-like matrix representation of the multidimensional Einstein-Kalb-Ramond theory is developed and the O(d,d)-symmetry is presented in the matrix-valued SL(2,R)-form. The an…
Hidden Symmerties in Dilaton--Axion Gravity
D. V. Gal'tsov, O. V. Kechkin
Four--dimensional Einstein--Maxwell--dilaton--axion system restricted to space--times with one non--null Killing symmetry is formulated as the three--dimensional gravity coupled si…
