Dirac-Kahler equations on curved spacetimes
Ion I. Cotaescu
A Lagrangian theory giving rise to a version of the Dirac-Kahler equations on curved backgrounds is considered. The principal pieces are the general fields which have values in the…

Discrete O(1,4) transformations and new scalar quantum modes on the de Sitter spacetime
Ion I. Cotaescu
It is shown that the isometry group of the de Sitter spacetime includes two different three-dimensional Abelian subgroups which transform between themselves through a discrete isom…

The free Dirac spinors of the spin basis on the de Sitter expanding universe
Ion I. Cotaescu
It is shown that on the de Sitter space-time the global behavior of the free Dirac spinors in momentum representation is determined by several phases factors which are functions of…
