SEMINARS, HARVARD-MIT ALGEBRAIC GEOMETRY
November 29, 2022 3:00 pmI will discuss recent work calculating the top weight cohomology of the moduli space A_g of principally polarized abelian varieties of dimension g for small values of g. The key...

November 23, 2022 9:00 amThe Bistritzer-MacDonald (BM) model predicted the existence of the narrow bands in the magic-angle twisted bilayer graphene (MATBG), and nowadays is a starting point for most theoretical works. In this...

November 22, 2022 9:30 amRecent progress in AdS/CFT has provided a good understanding of how the bulk spacetime is encoded in the entanglement structure of the boundary CFT. However, little is known about how...

Gauge Theory and Topology Seminar, SEMINARS
November 18, 2022 3:30 pmBeyond the tight/overtwisted dichotomy, 3-dimensional contact topology would appear to be dominated by flexibility: a central result of Eliashberg and Mishachev says that the contactomorphism group of the standard contact...

November 18, 2022 11:00 amIn string theory one finds that states become massless as one approaches boundaries in Calabi-Yau moduli spaces. In this talk we look in the opposite direction, that is, we search...

ALGEBRAIC DYNAMICS, SEMINARS
November 17, 2022 4:00 pmMcMullen proved that a stable family of rational maps is either trivial or all its members are Lattès. His proof relies on Thurston's theorem on postcritically finite maps, which uses...

November 16, 2022 4:15 pmI will discuss joint work with Christin Bibby, Nir Gadish, and Claudia Yun. The historical antecedents are in earlier work of Billera-Holmes-Vogtmann around 2000 and others, who study an interesting space of metric...
