SEMINARS, HARVARD-MIT ALGEBRAIC GEOMETRY
April 25, 2023 3:00 pmIn this talk, we investigate meromorphic differentials on the Riemann sphere with a single zero and several poles of predetermined orders. Our aim is to determine the number of such...

April 21, 2023 4:15 pmChip-firing games on finite graphs provide a combinatorial analog of the theory of special divisors on algebraic curves. Each chip configuration determines two numbers: the degree and rank, analogous to...
