Gabriëlle Zwaneveld gave a talk on oriented graphs with the same number of neighbors and second neighbors at each vertex at the Discrete Math Seminar

On September 15, 2026, Gabriëlle Zwaneveld from University of Amsterdam gave a talk on oriented graphs with the same number of neighbors and second neighbors at each vertex, motivated by Seymour’s second neighborhood conjecture, at the Discrete Math Seminar. The title of her talk was “On Seymour-tight orientations“.
