Almost Commutative Terwilliger Algebras II: Strong Gelfand Pairs
Nicholas L. Bastian, Stephen P. Humphries
Terwilliger algebras are a subalgebra of a matrix algebra constructed from an association scheme. In 2010, Tanaka defined what it means for a Terwilliger algebra to be almost commu…

Almost Commutative Terwilliger Algebras of Group Association Schemes I: Classification
Nicholas L. Bastian, Stephen P. Humphries
Terwilliger algebras are a subalgebra of a matrix algebra that are constructed from association schemes over finite sets. In 2010, Rie Tanaka defined what it means for a Terwillige…
