Let \( F \) be a \( p \) -adic field and let \( G = SL(2) \) be the group of unimodular \( 2{\times}2 \) matrices over \( F \) . The aim of this paper is to calculate certain equivariant homology groups attached to the action of \( G \) on its tree. They arise in connection with a theorem of M. Pimsner on the \( K \) -theory of the \( C^* \) -algebra of \( G \) [1986], and our purpose is to explore the representation theoretic content of Pimsner’s result.

Let \( \mathcal{H}(G) \) be the Hecke algebra of a reductive \( p \) -adic group \( G \) . We formulate a conjecture for the ideals in the Bernstein decomposition of \( \mathcal{H}(G) \) . The conjecture says that each ideal is geometrically equivalent to an algebraic variety. Our conjecture is closely related to Lusztig’s conjecture on the asymptotic Hecke algebra. We prove our conjecture for \( \mathrm{SL}(2) \) and \( \mathrm{GL}(n) \) . We also prove part (1) of the conjecture for the Iwahori ideals of the groups \( \mathrm{PGL}(n) \) and \( \mathrm{SO}(5) \) . The conjecture, if true, leads to a parametrization of the smooth dual of \( G \) by the points in a complex affine locally algebraic variety.

In the representation theory of reductive \( p \) -adic groups \( G \) , the issue of reducibility of induced representations is an issue of great intricacy. It is our contention, expressed as a conjecture in [2007], that there exists a simple geometric structure underlying this intricate theory.
We will illustrate here the conjecture with some detailed computations in the principal series of \( \mathrm{G}_2 \) .
A feature of this article is the role played by cocharacters \( h_{\mathbf{c}} \) attached to two-sided cells \( \mathbf{c} \) in certain extended affine Weyl groups.
The quotient varieties which occur in the Bernstein programme are replaced by extended quotients. We form the disjoint union \( \mathfrak{A}(G) \) of all these extended quotient varieties. We conjecture that, after a simple algebraic deformation, the space \( \mathfrak{A}(G) \) is a model of the smooth dual \( \textrm{Irr}(G) \) . In this respect, our programme is a conjectural refinement of the Bernstein programme.
The algebraic deformation is controlled by the cocharacters \( h_{\mathbf{c}} \) . The cocharacters themselves appear to be closely related to Langlands parameters.

We prove that a strengthened form of the local Langlands conjecture is valid throughout the principal series of any connected split reductive \( p \) -adic group. The method of proof is to establish the presence of a very simple geometric structure, in both the smooth dual and the Langlands parameters. We prove that this geometric structure is present, in the same way, for the general linear group, including all of its inner forms. With these results as evidence, we give a detailed formulation of a general geometric structure conjecture.

This expository paper first reviews some basic facts about \( p \) -adic fields, reductive \( p \) -adic groups, and the local Langlands conjecture. If \( G \) is a reductive \( p \) -adic group, then the smooth dual of \( G \) is the set of equivalence classes of smooth irreducible representations of \( G \) . The representations are on vector spaces over the complex numbers. In a canonical way, the smooth dual is the disjoint union of subsets known as the Bernstein components. According to a conjecture due to ABPS (Aubert–Baum–Plymen–Solleveld), each Bernstein component has a geometric structure given by an appropriate extended quotient. The paper states this ABPS conjecture and then indicates evidence for the conjecture, and its connection to the local Langlands conjecture.

Let \( G \) be a reductive \( p \) -adic group. We study how a local Langlands correspondence for irreducible tempered \( G \) -representations can be extended to a local Langlands correspondence for all irreducible smooth representations of \( G \) . We prove that, under a natural condition involving compatibility with unramified twists, this is possible in a canonical way.
To this end we introduce analytic \( \mathrm{R} \) -groups associated to non-tempered essentially square-integrable representations of Levi subgroups of \( G \) . We establish the basic properties of these new \( \mathrm{R} \) -groups, which generalize Knapp–Stein \( \mathrm{R} \) -groups.

Let \( F \) be a non-archimedean local field. We establish the local Langlands correspondence for all inner forms of the group \( \mathrm{SL}_n(F) \) . It takes the form of a bijection between, on the one hand, conjugacy classes of Langlands parameters for \( \mathrm{SL}_n(F) \) enhanced with an irreducible representation of an \( \mathrm{S} \) -group and, on the other hand, the union of the spaces of irreducible admissible representations of all inner forms of \( \mathrm{SL}_n(F) \) up to equivalence. An analogous result is shown in the archimedean case. For \( p \) -adic fields, this is based on the work of Hiraga and Saito. To settle the case where \( F \) has positive characteristic, we employ the method of close fields. We prove that this method is compatible with the local Langlands correspondence for inner forms of \( \mathrm{GL}_n(F) \) , when the fields are close enough compared to the depth of the representations.

Let \( F \) be a non-Archimedean local field, and let \( G^{\sharp} \) be the group of \( F \) -rational points of an inner form of \( \mathrm{SL}_n \) . We study Hecke algebras for all Bernstein components of \( G^{\sharp} \) , via restriction from an inner form \( G \) of \( \mathrm{GL}_n(F) \) .
For any packet of \( \mathrm{L} \) -indistinguishable Bernstein components, we exhibit an explicit algebra whose module category is equivalent to the associated category of complex smooth \( G^{\sharp} \) -representations. This algebra comes from an idempotent in the full Hecke algebra of \( G^{\sharp} \) , and the idempotent is derived from a type for \( G \) . We show that the Hecke algebras for Bernstein components of \( G^{\sharp} \) are similar to affine Hecke algebras of type \( A \) , yet in many cases are not Morita equivalent to any crossed product of an affine Hecke algebra with a finite group.

Let \( \mathscr{G} \) be a split connected reductive group over a local non-Archimedean field. We classify all irreducible complex \( \mathscr{G} \) -representations in the principal series, irrespective of the (dis)connectedness of the center of \( \mathscr{G} \) . This leads to a local Langlands correspondence for principal series representations of \( \mathscr{G} \) . It satisfies all expected properties, in particular it is functorial with respect to homomorphisms of reductive groups. At the same time, we show that every Bernstein component \( \mathfrak{s} \) in the principal series has the structure of an extended quotient of Bernstein’s torus by Bernstein’s finite group (both attached to \( \mathfrak{s} \) ).

Let \( G \) be any reductive \( p \) -adic group. We discuss several conjectures, some of them new, that involve the representation theory and the geometry of \( G \) .
At the heart of these conjectures are statements about the geometric structure of Bernstein components for \( G \) , both at the level of the space of irreducible representations and at the level of the associated Hecke algebras. We relate this to two well-known conjectures: the local Langlands correspondence and the Baum–Connes conjecture for \( G \) . In particular, we present a strategy to reduce the local Langlands correspondence for irreducible \( G \) -representations to the local Langlands correspondence for supercuspidal representations of Levi subgroups.
