Bilinearized Legendrian contact homology and the augmentation category

F Bourgeois, B Chantraine - 2014 - projecteuclid.org
In this paper, we construct an A_∞-category associated to a Legendrian submanifold of a jet
space. Objects of the category are augmentations of the Chekanov algebra A(Λ) and the …
