Research Abstract |
I tried to develop a new theory of codes and designs on association schemes based on the (noncommutative) Terwilliger algebra in place of the (commutative) Bose-Mesner algebra. The outcome of the research includes a fundamental contribution to the theory of width and dual width by Brouwer et al., as well as applications of new tools such as semidefinite programming and Leonard pairs.
