Verlinde ring

Contents

Idea

For GG a suitable Lie group, the Verlinde ring is the collection of isomorphism classes of positive energy representations of the corresponding loop group, equipped with the “fusion” tensor product.

The Verlinde ring is also understood as being the ring of equivariant twisted K-theory classes on GG (FHT) and, essentially equivalently, of Chan-Paton gauge fields over D-branes in the WZW model (see there for further references).
