Sabloff duality is an analogue of Poincaré duality for Legendrian contact homology, which is a Floer-theoretic invariant of Legendrian knots. In this talk, I will tell you about an A-infinity enhancement of Sabloff duality. If time permits, I will also mention higher homotopies for this enhanced duality.
