CalTitle1: $osp(1,2)$, the Bannai-Ito Algebra and Generalizations

Auth: leo@122-56-205-245.mobile.spark.co.nz (ltzo2369) in SMS-WASM

The Bannai-Ito algebra and its relation to the Bannai-Ito polynomials will be reviewed. Emphasis will be put on some of the connections with the Lie superalgebra osp(1,2)osp(1,2). Centralizing elements of osp(1,2)osp(1,2) associated to involutions will be identified and used to realize the Bannai-Ito algebra as the centralizer of osp(1,2)osp(1,2) in its co-product embedding in the three-fold direct product of this algebra with itself. The centralizing elements will be called upon to obtain a higher rank generalization and a hyperoctahedral version of the Bannai-Ito algebra. About the speaker: Luc Vinet is Aisenstadt Professor of Physics at the UniversitÃ© de MontrÃ©al and the Director of the CRM (Centre de Recherches MathÃ©matiques) , a position he held previously from 1993 to 1999. Born in MontrÃ©al, he holds a doctorate (3rd cycle) from the UniversitÃ© Pierre et Marie Curie (Paris) and a PhD from the UniversitÃ© de MontrÃ©al, both in theoretical physics. After two years as a research associate at MIT, he was appointed as assistant professor in the Physics Department at the UniversitÃ© de MontrÃ©al in the early 1980s and promoted to full professorship in 1992. His research interests in theoretical and mathematical physics include: exactly solvable problems, symmetries, algebraic structures, special functions and quantum information, topics in which he written over 250 papers. In 1999, Luc Vinet joined the ranks of McGill University where he held the position of Vice-Principal (Academic) and Provost. From 2005 to 2010, he was the Rector of the UniversitÃ© de MontrÃ©al. Among numerous honours, he was awarded the Armand-Frappier Prize of the Government of QuÃ©bec in 2009 and the 2012 CAP-CRM Prize in Theoretical and Mathematical Physics. He also holds an honorary doctorate from the UniversitÃ© Claude-Bernard (Lyon). He is a Fellow of the American Mathematical Society and was appointed Officer of the National Order of Quebec in 2017.
