Combinatorics around the q-Onsager algebra

Important announcement

Due to the current pandemic, we are postponing the q-Onsager Algebra Conference until the week of 28 June to 3 July 2021.

We were deeply saddened to hear about the passing of Vaughan Jones, who was scheduled to speak at our conference.  We extend our heartfelt sympathies to his family, friends and colleagues.  (link)


At the conference we will be celebrating the 65th birthday of Paul Terwilliger. As such, the general theme of this conference will be the mathematical topics that Paul has worked on over the years (which all have relationships to the q-Onsager algebra). These topics include the following:

• Topics in algebraic graph theory, such as distance-regular graphs, association schemes, the subconstituent algebra, and the Q-polynomial property;

• Topics in linear algebra, such as Leonard pairs, tridiagonal pairs, billiard arrays, lowering-raising triples, and a linear algebraic approach to the orthogonal polynomials of the Askey scheme;

• Topics in Lie theory, such as the tetrahedron algebra and the Onsager algebra;

• Topics in algebras and their representations, such as the equitable presentation of Uq(sl2), the q-tetrahedron algebra, the q-Onsager algebra in mathematical physics, and the universal Askey-Wilson algebra.

The deadline for submitting abstracts for contributed talks has passed.  However, further submissions may still be considered if space is available.  If interested, please email the conference organizers.
