摘要：

In previous work we analysed the algebra of observables of the initial data surface SIGMA-2 for 2 + 1 de Sitter gravity, and constructed for genus 2 the group of autmorphisms H of the homotype group pi-1 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.
