A Maximally Symmetric Vector Propagator
We derive the propagator for a massive vector field on a de Sitter background of arbitrary dimension. This propagator is de Sitter invariant and possesses the proper flat spacetime and massless limits. Moreover, the retarded Green’s function inferred from it produces the correct classical response to a test source. Our result is expressed in a tensor basis which is convenient for performing qua...
متن کاملSpinor Parallel Propagator and Green’s Function in Maximally Symmetric Spaces
We introduce the spinor parallel propagator for maximally symmetric spaces in any dimension. Then, the Dirac spinor Green’s functions in the maximally symmetric spaces Rn, Sn and Hn are calculated in terms of intrinsic geometric objects. The results are covariant and coordinate-independent. ∗E-mail address: [email protected]
متن کاملMaximally symmetric trees
We characterize the “best” model geometries for the class of virtually free groups, and we show that there is a countable infinity of distinct “best” model geometries in an appropriate sense–these are the maximally symmetric trees. The first theorem gives several equivalent conditions on a bounded valence, cocompact tree T without valence 1 vertices saying that T is maximally symmetric. The sec...
متن کاملMultipartite maximally entangled states in symmetric scenarios
We consider the class of (N + 1)-partite states suitable for protocols where there is a powerful party, the authority, and the other N parties play the same role, namely, the state of their system lies in the symmetric Hilbert space. We show that, within this scenario, there is a “maximally entangled state” that can be transform by a local operations and classical communication protocol into an...
متن کاملDifferential Invariants of Maximally Symmetric Submanifolds
Let G be a Lie group acting smoothly on a manifold M . A closed, nonsingular submanifold S ⊂M is called maximally symmetric if its symmetry subgroup GS ⊂ G has the maximal possible dimension, namely dimGS = dimS, and hence S = GS · z0 is an orbit of GS . Maximally symmetric submanifolds are characterized by the property that all their differential invariants are constant. In this paper, we expl...
