Non-Null Torus Knotted Gravitational Waves from Gravitoelectromagnetism
R. S. Facundo, I. V. Vancea
In this paper, we construct a non-null torus-knotted gravitational monochromatic wave solution of the linearized Einstein equations in vacuum, employing the gravitoelectromagnetic…
On The Symplectic Two-Form of Gravity in Terms of Dirac Eigenvalues
M. C. B. Abdalla, M. A. De Andrade, M. A. Santos +1
The Dirac eigenvalues form a subset of observables of the Euclidean gravity. The symplectic two-form in the covariant phase space could be expressed, in principle, in terms of the…
On Local Constraints of D=4 Supergravity in Terms of Dirac Eigenvalues
N. Pauna, I. V. Vancea
It has been recently shown that in order to have Dirac eigenvalues as observables of Euclidean supergravity, certain constraints should be imposed on the covariant phase space as w…
Constraints on spacetime manifold in Euclidean supergravity in terms of Dirac eigenvalues
C. Ciuhu, I. V. Vancea
We generalize previous work on Dirac eigenvalues as dynamical variables of Euclidean supergravity. The most general set of constraints on the curvatures of the tangent bundle and o…
Gravity and Duality between Coordinates and Matter Fields
I. V. Vancea
We use the duality between the local Cartezian coordinates and the solutions of the Klein-Gordon equation to parametrize locally the spacetime in terms of wave functions and prepot…
Euclidean Supergravity in Terms of Dirac Eigenvalues
I. V. Vancea
It has been recently shown that the eigenvalues of the Dirac operator can be considered as dynamical variables of Euclidean gravity. The purpose of this paper is to explore the pos…
