Chekanov torus and Gelfand--Zeitlin torus in
Yoosik Kim
The Chekanov torus was the first known \emph{exotic} torus, a monotone Lagrangian torus that is not Hamiltonian isotopic to the standard monotone Lagrangian torus. We explore the r…

Disk potential functions for quadrics
Yoosik Kim
We compute the disk potential of Gelfand--Zeitlin monotone torus fiber in a quadric hypersurface by exploiting toric degenerations, Lie theoretical mirror symmetry, and the structu…
