Abstract
In this talk, I will present a chain-level analogue of the persistence module, called a filtered chain complex, together with its parallel theory on barcodes and stability phenomenon. Next, I will elaborate on an infinite-dimensional Morse theory naturally born in both symplectic and contact geometry, called the Hamiltonian Floer homology. The main part of this talk will be several examples (and theorems) that illustrate how chain-level persistence can be used to solve quantitative questions in symplectic geometry and symplectic dynamics. This is mostly a survey talk based on my related results in recent years.
