The Levi-Civita tensor noncovariance and curvature in the pseudotensors space
A. L. Koshkarov
It is shown that conventional "covariant" derivative of the Levi-Civita tensor is not really covariant. Adding compensative terms, it is possible to make it covariant and to be equ…
Nonabelian duality and analytic continuation of instantons
A. L. Koshkarov
Within the framework of the gauge O(1,3)\times O(1,3)-theory, an extension of the Belavin-Polyakov-Schwarz-Tyupkin ansatz is proposed by incorporation there the Levi-Civita tensor.…
On General Relativity extension
A. L. Koshkarov
The careful analysis of the duality properties of Riemann's curvature tensor points to possibility of extension of Einstein's General Relativity to the nonabelian Yang-Mills theory…
Dual Symmetry in Gauge Theories
A. L. Koshkarov
Continuous dual symmetry in electrodynamics, Yang-Mills theory and gravitation is investigated. Dual invariant which leads to badly nonlinear motion equations is chosen as a Lagran…
