On restriction rules from $Gl(N)$ to $O(N)$
Abstract:
We show that the Grothendieck semiring of $O(N)$ is a quotient of the one of $O(\infty)$. Using this, we can express restriction multiplicities from $GL(N)$ to $O(N)$ via an alternating sum formula over the elements of a reflection group in terms of classical multiplicites due to Littlewood.
