  Abstract

   

We will discuss the Plancherel formula of an affine Hecke algebra and its applications to the harmonic analysis of reductive p-adic groups.We hope to discuss the following topics:

-Affine Hecke algebras.

-Hilbert algebra structure of an affine Hecke algebra.

-The abstract Plancherel formula.

-The trace on the Bernstein basis.

-The mu function of the Hecke algebra.

-Residue calculus for the trace functional, and the support theorem.

-The Schwartz completion of the Hecke algebra.

-The comparison theorem for algebraic and tempered extensions.

-The classification of the discrete series and their formal degrees.

-Borel's theorem and Hecke algebras of types for reductive p-adic groups.

-Unipotent representations of unramified absolutely quasi-simple groups.
