Special Year Seminar

In this learning seminar talk, I will explain the local picture underlying the technique of defining integer-valued curve counts, known as the FOP perturbation (named after Fukaya-Ono and B. Parker). The problem is indeed very simple: given a finite...

In this talk, we introduce a non-linear symplectic capacity for four-dimensional Euclidean domains $X$, known as the shape invariant of $X$, which encodes the embeddability of Lagrangian tori into $X$. We present a computational framework for this...
