Exact Lagrangian fillability of 3-braid closures
James Hughes, Jiajie Ma
We determine when a Legendrian quasipositive 3-braid closure in standard contact admits an orientable or non-orientable exact Lagrangian filling. Our main result pro…

Weak Relative Calabi-Yau Structures for Legendrian Contact Homology
Jiajie Ma, Joshua M. Sabloff
Legendrian Contact Homology (LCH) and its augmentations are important invariants of Legendrian submanifolds, and for Legendrian knots in the standard contact 3-space in particular.…
