Legendrian contact homology in ${\mathbb{R}}^3$

Abstract

This is an introduction to Legendrian contact homology and the Chekanov-Eliashberg differential graded algebra, with a focus on the setting of Legendrian knots in ${\mathbb{R}}^3$. This is the published version of the paper, but with a section of errata added at the end.

v5: 60 pages. This is the published version but we have added a page of errata that were discovered after publication
