Abstract

We show that there exists a Legendrian knot with maximal Thurston–Bennequin invariant whose contact homology is trivial. We also provide another Legendrian knot which has the same knot type and classical invariants but nonvanishing contact homology We show that there exists a Legendrian knot with maximal Thurston–Bennequin invariant whose contact homology is trivial.
