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…

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 I: The Group Association Scheme

Nicholas L. Bastian, Stephen P. Humphries

Terwilliger algebras are a subalgebra of a matrix algebra constructed from an association scheme. Rie Tanaka defined what it means for a Terwilliger algebra to be almost commutativ…

Almost Commutative Terwilliger Algebras of Group Association Schemes II: Primitive Idempotents

Nicholas L. Bastian

This paper is a continuation of Almost Commutative Terwilliger Algebras of Group Association Schemes I: Classification [1]. In that paper, we found all groups G for which the Terwi…

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…

On Schur Rings over Infinite Groups III

Nicholas Bastian, Andrew Misseldine

In the paper, we develop further the properties of Schur rings over infinite groups, with particular emphasis on the virtually cyclic group , where is a prime. We…

On Schur Rings Over Infinite Groups

Nicholas Bastian, Jaden Brewer, Andrew Misseldine

Schur rings are a type of subring of the group ring that is spanned by a partition of the group that meets certain conditions. Past literature has exclusively focused on the finite…
