On October 6, 2026, Daniel McGinnis from the IBS Discrete Mathematics Group gave a talk at the Discrete Math Seminar on a commutative-algebraic approach to regularity that yields an optimal colorful fractional Helly theorem for d-Leray simplicial complexes. The title of his talk was “Multi-generic initial ideals, regularity, and the optimal colorful fractional Helly theorem for d-Leray complexes“.
