Simplicial rapid decay algebras associated to a discrete group, by Crichton Ogle

This is an updated version of my K-theory archives posting 63. Together with the next it proves rational injectivity of the assembly map for the topological K-theory of the reduced C^*-algebra C^*(pi) for any countable discrete group \pi (the first version demonstrated injectivity for a C^*-algebra constructed from a presentation of pi. This implied the result for the maximal C^*-algebra, but not the reduced).
