The de Sitter QED in Coulomb gauge: first order transition amplitudes
Ion I. Cotaescu, Cosmin Crucean
We construct the de Sitter QED in Coulomb gauge assuming that the quantum modes are prepared by a global apparatus which is able to determine a stable and invariant vacuum state, i…

The physical meaning of the de Sitter invariants
Ion I. Cotaescu
We study the Lie algebras of the covariant representations transforming the matter fields under the de Sitter isometries. We point out that the Casimir operators of these represent…
