Schur rings over cyclic groups having Almost Commutative Terwilliger algebras
Nicholas L. Bastian, Stephen P. Humphries
Terwilliger algebras are subalgebras of a matrix algebra constructed from an association scheme. Rie Tanaka defined what it means for a Terwilliger algebra to be almost commutative…
