Speaker: Istvan Tomon
I will talk about three long-standing conjectures from the intersection of linear algebra and combinatorics that turn out to be closely related: the Alon-Jaeger-Tarsi conjecture (1988) on non-vanishing linear maps, the Additive basis conjecture of Alon-Linial-Meshulem (1991), and a conjecture of Pyber (1996) on coset covers of abelian groups. Recently, we solved the first one in a strong form, the second one in a weak form, and the third one in just the right form. Based on joint works with Janos Nagy and Peter Pal Pach.
