Topology Seminar (Introductory Talk): Computations of the Chekanov-Eliashberg algebra

The Chekanov-Eliashberg algebra is a powerful Legendrian isotopy invariant that is defined by counts of pseudoholomorphic discs. We give an introduction to both analytical and algebraic aspects of the theory, perform calculations in both low and high dimension, and present some open problems.
