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…
Symplectic Gravity Models in Four, Three and Two Dimensions
O. Kechkin, M. Yurova
A class of the gravity models describing a coupled system of Abelian vector fields and the symmetric matrix generalizations of the dilaton and Kalb-Ramond fi…
U(1,1)--Invariant Generation of Charges for Einstein--Maxwell--Dilaton--Axion Theory
O. Kechkin, M. Yurova
The action of the isometry subgroup which preserves the trivial values of the fields is studied for the stationary D=4 Einstein--Maxwell--Dilaton--Axion theory. The technique for g…
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…
Kramer--Neugebauer Transformation for Einstein--Maxwell--Dilaton--Axion Theory
O. Kechkin, M. Yurova
The Kramer--Neugebauer--like transformation is constructed for the stationary axisymmetric D=4 Einstein--Maxwell--dilaton--axion system. This transformation directly maps the duali…
