Homology of the Lie Algebra of Locally Generated Derivations of a Discrete and Proper Metric Space

Nigel Higson, Tsuyoshi Kato

We associate to each proper discrete metric space a Lie algebra that acts by locally generated derivations on an infinite tensor product of matrix algebras indexed by the point…

Lie groupoids, the Satake compactification and the tempered dual, I: The Satake groupoid

Jacob Bradd, Nigel Higson, Robert Yuncken

The (maximal) Satake compactification associated to a real reductive group is the closure of the symmetric space of all maximal compact subgroups of within the compact spac…

Lie groupoids, the Satake compactification and the tempered dual, II: The Harish-Chandra principle

Jacob Bradd, Nigel Higson, Robert Yuncken

We give a geometric account of Harish-Chandra's principle that a tempered irreducible representation of a real reductive group is either square-integrable modulo center, or embedda…

A Mackey embedding for reduced C*-algebras of real reductive groups

Pierre Clare, Nigel Higson, Angel Román

The purpose of this paper is construct an embedding of the C*-algebra of the Cartan motion group of a real reductive group G into the reduced C*-algebra of G itself. The embedding…

Pseudodifferential operators and the Connes-Kasparov isomorphism

Peter DeBello, Nigel Higson

We compute the K-theory of the C*-category generated by order zero, equivariant, properly supported, classical pseudodifferential operators acting on sections of homogeneous bundle…

Operator K-Theory and Tempiric Representations

Jacob Bradd, Nigel Higson, Robert Yuncken

David Vogan proved that if is a real reductive group, and if is a maximal compact subgroup of , then every irreducible representation of is included as a minimal …

On the Connes-Kasparov isomorphism, II: The Vogan classification of essential components in the tempered dual

Pierre Clare, Nigel Higson, Yanli Song

This is the second of two papers dedicated to the computation of the reduced C*-algebra of a connected, linear, real reductive group up to C*-algebraic Morita equivalence, and the…
