In previous work we analysed the algebra of observables of the initial data surface Σ2 for 2+1 de Sitter gravity, and constructed for genus 2 the group of automorphisms H of the homotopy group π1 induced by the mapping class group. The group H induces a group D of canonical transformations on the algebra of observables which is related to the braid group. Here all of the previous results are implemented for any genus and at the quantum level.

Abstract

In previous work we analysed the algebra of observables of the initial data surface Σ2 for 2+1 de Sitter gravity, and constructed for genus 2 the group of automorphisms H of the homotopy group π1 induced by the mapping class group. The group H induces a group D of canonical transformations on the algebra of observables which is related to the braid group. Here all of the previous results are implemented for any genus and at the quantum level.
