SYZ Mirror Symmetry & Gross-Siebert
Spring 2026
Spring 2026
We will meet on Thursdays from 2:45PM to 4:15PM at 2-255, for a 1 hour talk followed by a 30 minute discussion session.
The goal of this reading seminar is to understand some parts of the Gross-Siebert program. We will start with the basics of SYZ mirror symmetry, Lagrangian fibrations and discuss a specific example due to Abouzaid-Sylvan. After the spring break, we will cover some aspects of the Gross-Siebert program, following the references below. The first half will be of a symplectic flavor, while we expect the second half to be closer to algebraic (logarithmic) geometry.
Please feel free to ask questions to the organizers Yonghwan Kim (yonghkim@mit.edu) and Honghao Jing (honghao@math.harvard.edu).
We also have two mentors (Sam and Sebastian), so reach out for help if you need help preparing the talks.
