Anatomy of big algebras

Tamás Hausel, Institute of Science and Technology Austria

SMRI Seminar, 16th October 2025

1 pm – 2 pm, SMRI Seminar Room (A12 Macleay Room 301)

Abstract: Starting with Schrodinger’s critique of the difficulty of visualising Heisenberg’s matrix quantum physics we will discuss the notion of non-commutative matrices and its use in particle physics via Gell-Mann’s eightfold way describing heavy particles in terms of quarks. Then I will use these backgrounds to motivate my recent work on big algebras — commutative avatars of non-commutative matrix representations — and show some visualisation of them to highlight their complex anatomy, shedding some new light on the quantum numbers of the heavy particles in the baryon octet and decuplet.
