SEMINARS, HARVARD-MIT ALGEBRAIC GEOMETRY
October 11, 2022 3:00 pmThe minimal model program is an ambitious program that aims to understand the geometry of complex projective varieties (eg. manifolds defined by polynomial equations). In this talk we will discuss...

SEMINARS, CMSA EVENTS
October 7, 2022 9:30 amIn this talk, we construct special Lagrangian fibrations for log Calabi--Yau surfaces and scattering diagrams from Lagrangian Floer theory of the fibers. These scattering diagrams recover the algebro-geometric scattering diagrams...

Gauge Theory and Topology Seminar, SEMINARS
October 7, 2022 3:30 pmWe will talk about our recent construction of the smallest closed exotic 4-manifolds with signature zero known to date. Our novel examples are derived from fairly special small Lefschetz fibrations...
