Superselection sectors in the Ashtekar-Horowitz-Boulware model

Jorma Louko, Alberto Molgado

We investigate refined algebraic quantisation of the constrained Hamiltonian system introduced by Boulware as a simplified version of the Ashtekar-Horowitz model. The dimension of…

SO_0(1,d+1) Racah coefficients: Type I representations

Kirill Krasnov, Jorma Louko

We use AdS/CFT inspired methods to study the Racah coefficients for type I representations of the Lorentz group SO_0(1,d+1) with d>1. For such representations (a multiple of) the R…
