New Action Principle for General Relativity
Kirill Krasnov
General Relativity can be reformulated as a diffeomorphism invariant SU(2) gauge theory. A new action principle for this "pure connection" formulation of GR is described.
A Unified Theory of Non-Linear Electrodynamics and Gravity
Alexander Torres-Gomez, Kirill Krasnov, Carlos Scarinci
We describe a class of unified theories of electromagnetism and gravity. The Lagrangian is of the BF type, with a potential for the B-field, the gauge group is U(2) (complexified).…
Motion of a "small body" in non-metric gravity
Kirill Krasnov
We describe "small bodies" in a non-metric gravity theory previously studied by this author. The main dynamical field of the theory is a certain triple of two-forms rather than the…
Plebanski gravity without the simplicity constraints
Kirill Krasnov
In Plebanski's self-dual formulation general relativity becomes SO(3) BF theory supplemented with the so-called simplicity (or metricity) constraints for the B-field. The main dyna…
Remarks on Barbero-Immirzi parameter as a field
Alexander Torres-Gomez, Kirill Krasnov
We revisit a propagating torsion gravity theory obtained by introducing a field coupled to the Holst term in the first-order Einstein-Cartan action. The resulting theory has second…
Hamiltonian Analysis of non-chiral Plebanski Theory and its Generalizations
Sergei Alexandrov, Kirill Krasnov
We consider non-chiral, full Lorentz group-based Plebanski formulation of general relativity in its version that utilizes the Lagrange multiplier field Phi with "internal" indices.…
