Canonical Commutation Relations: A quick proof of the Stone-von Neumann theorem and an extension to general rings

Bachir Bekka

Let $R$ be a (not necessary commutative) ring with unit, $d \geq 1$ an integer, and $λ$ a unitary character of the additive group $(R, +) .$ A pair $(U, V)$ of unitary representations…

The $L_{p}$ -dual space of a semisimple Lie group

Bachir Bekka

Let $G$ be a semisimple Lie group. We describe the irreducible representations of $G$ by linear isometries on $L_{p}$ -spaces for $p \in (1, + \infty)$ with $p \neq = 2.$ More precisely, we…

On unitary representations of algebraic groups over local fields

Bachir Bekka, Siegfried Echterhoff

Let $G$ be an algebraic group over a local field $k$ of characteristic zero. We show that the locally compact group $G (k)$ consisting of the $\math…
