Péter Pál Pach gave an online talk on the solution of the Alon-Jaeger-Tarsi conjecture at the Virtual Discrete Math Colloquium

On September 30, 2021, Péter Pál Pach from the Budapest University of Technology and Economics gave an online talk at the Virtual Discrete Math Colloquium on the solution of the Alon-Jaeger-Tarsi conjecture for all finite fields of size more than 61 but not equal to 79. The title of his talk was “The Alon-Jaeger-Tarsi conjecture via group ring identities“.
