Geometry and topology of the tempered Iwahori-spherical representations of a split semisimple -adic group
Dominic Majda, Graham A. Niblo, Roger Plymen +1
Let be a connected split -adic group of type , or . Amongst the tempered representations of a key role is played by the Iwahori-sph…
Building weight-free Følner sets for Yu's Property A in coarse geometry
Graham Niblo, Nick Wright, Jiawen Zhang
In this note we study the natural question of when the generalised Følner sets exhibiting property A can be chosen to be subsets of the space itself. We show that for many property…
Centralisers, complex reflection groups and actions in the Weyl group
Graham A. Niblo, Roger Plymen, Nick Wright
The compact, connected Lie group admits two forms: simply connected and adjoint type. As we previously established, the Baum-Connes isomorphism relates the two Langlands dual…
Coarse median algebras: The intrinsic geometry of coarse median spaces and their intervals
Graham A. Niblo, Nick Wright, Jiawen Zhang
This paper establishes a new combinatorial framework for the study of coarse median spaces, bridging the worlds of asymptotic geometry, algebra and combinatorics. We introduce a si…
Poincaré duality and Langlands duality for extended affine Weyl groups
Graham A. Niblo, Roger Plymen, Nick Wright
In this paper we construct an equivariant Poincaré duality between dual tori equipped with finite group actions. We use this to demonstrate that Langlands duality induces a rationa…
A four point characterisation for coarse median spaces
Graham A. Niblo, Nick Wright, Jiawen Zhang
Coarse median spaces simultaneously generalise the classes of hyperbolic spaces and median algebras, and arise naturally in the study of the mapping class groups and many other con…
