Riemannian Structure imposed on Friedmann and more general spacetimes
Marta Dudek, Janusz Garecki
In the paper we consider two Finsler-like Riemannian metrics, which can be in a natural way introduced into general relativity. One of those metrics is degenerate and the…
Ehreshmann theory of connection in a principal bundle - compendium for physicists
Marta Dudek, Janusz Garecki
In the paper we give a compendium about theory of connection. We think that this compendium will be useful for young relativists.
General relativity with nonzero cosmological constant as a gauge theory
Marta Dudek, Janusz Garecki
We show in a new way that the general relativity action (and Lagrangian)in recent Einstein-Palatini formulation is equivalent in four dimensions to the action (and Lagrangian) of a…
General relativity with a positive cosmological constant as a gauge theory
Marta Dudek, Janusz Garecki
In the paper we show that the general relativity action (and Lagrangian) in recent Einstein-Palatini formulation is equivalent to the action (and Langrangian) of a gauge field. We…
