Abstract:In this talk we present a structure theory for a class of table algebras, i.e. the so-called quasi-thin table algebras. They are direct generalizations of quasi-thin association schemes. Although this class of table algebras is rather close to finite groups, its structural properties are quite different from finite group theory. The thin radical and thin residue give rise to two group structures for every table algebra. They play the central role in our discussions. Applications to association schemes are also discussed, and some new results about quasi-thin association schemes are obtained. This is a joint work with M. Muzychuk.
