Scalar Spinor Cosmological Model And Covariant Formalism Request Pdf In this work, we investigate a cosmological model in the context of the covariant formalism proposed by canuto et al. where the notion of atomic and gravitational units is invoked. We investigate a cosmological model using the covariant formalism proposed by canuto et al., considering bosonic and fermionic fields as sources, including both self interacting potentials.
Pdf General Covariant Evolution Formalism For Numerical Relativity Article "scalar spinor cosmological model and covariant formalism" detailed information of the j global is an information service managed by the japan science and technology agency (hereinafter referred to as "jst"). Publishes important review articles and original articles on the subject of particles and fields (high energy physics) and topics intersecting with gravitation and cosmology. He noether symmetry rendered the complete integration of the dynamical systems. the cosmological solutions showed that the spinor field can play the role of "inflaton" – non minimally coupled case –, such that its equation of state is similar to that of the cosmological constant;. The newman penrose formalism is introduced, a tetrad and spinor based calculus that decomposes curvature into five complex weyl scalars. one of these scalars, psi4, directly represents outgoing gravitational radiation, linking pure geometry to the signal measured by ligo.

Spinor representations exist only with respect to the local lorentz group, and the corresponding dirac equation in curved spacetime involves gamma matrices defined in a local inertial frame. the vielbein provides the map between this local frame and spacetime coordinates, while the affine spin connection enters the fermionic covariant derivative. In this work, we investigate a cosmological model in the context of the covariant formalism proposed by canuto et al. where the notion of atomic and gravitational units is invoked. Each component of a spinor transforms as a scalar function under general coor dinate transformations, so this kind of transformation is straightforward. however, the transformation of spinors under tetrad rotations requires additional formalism.
