On the role of constraints and degrees of freedom in the Hamiltonian formalism
Alexey Golovnev
Unfortunately, the Hamiltonian mechanics of degenerate Lagrangian systems is usually presented as a mere recipe of Dirac, with no explanation as to how it works. Then it comes to d…
The Variational principle, Conformal and Disformal transformations, and the degrees of freedom
Alexey Golovnev
Conformal and disformal transformations are now being very intensively studied in the context of various modified gravity theories. In particular, some special classes of them can…
Revisiting diagonal tetrads: New Black Hole solutions in gravity
Adel Awad, Alexey Golovnev, María-José Guzmán +1
We study various forms of diagonal tetrads that accommodate Black Hole solutions in gravity with certain symmetries. As is well-known, vacuum spherically symmetric diagonal…
Contemplating the fate of modified gravity
Alexey Golovnev, Maria-Jose Guzman
Possible models of modified gravity are being extensively studied now, with most phenomenological motivations coming from puzzles and tensions in cosmology due to a natural desire…
Lorentz gauge-invariant variables in torsion-based theories of gravity
Daniel Blixt, Rafael Ferraro, Alexey Golovnev +1
General relativity dynamics can be derived from different actions -- which depart from the Einstein-Hilbert action in boundary terms -- and for different choices of the dynamical v…
