Abstract: In this talk, we will prove that every Gelfand pair admits an Iwasawa decomposition.

Before that, we will explain what Gelfand pairs are and why Iwasawa decompositions are useful.

At the end, we will discuss a conjecture studied in collaboration with M. Kalantar and P.-E. Caprace, speculating about similar results for type I groups.

Noncommutative Geometry in NYC

Series comments: Noncommutative Geometry studies an interplay between spatial forms and algebras with non-commutative multiplication. Our seminar welcomes talks in Number Theory, Geometric Topology and Representation Theory linked to the context of Operator Algebras. All talks are kept at the entry-level accessible to the graduate students and non-experts in the field.
