Knotted Legendrian surfaces with few Reeb chords

preprint2011arXivOpen access

Abstract

For g>0g>0, we construct g+1g+1 Legendrian embeddings of a surface of genus gg into J1(R2)=R5J^1(R^2)=R^5 which lie in pairwise distinct Legendrian isotopy classes and which all have g+1g+1 transverse Reeb chords (g+1g+1 is the conjecturally minimal number of chords). Furthermore, for gg of the g+1g+1 embeddings the Legendrian contact homology DGA does not admit any augmentation over Z/2ZZ/2Z, and hence cannot be linearized. We also investigate these surfaces from the point of view of the theory of generating families. Finally, we consider Legendrian spheres and planes in J1(S2)J^1(S^2) from a similar perspective.
