Four-Weight Spin Models and Jones Pairs

Ada Chan, Chris Godsil, Akihiro Munemasa

Published 2001-11-02Version 1

We introduce and discuss Jones pairs. These provide a generalization and a new approach to the four-weight spin models of Bannai and Bannai. We show that each four-weight spin model determines a ``dual'' pair of association schemes.
