Bordered Legendrian Rational Symplectic Field Theory
Given a Legendrian knot $Λ\subset \mathbb{R}^3$ and a vertical line dividing the front projection of $Λ$ into two halves, we construct a differential graded algebra associated to each half-knot. We then show that one may obtain the commutative algebra from Legendrian Rational Symplectic Field Theory as a pushout of the two bordered algebras. This construction extends the bordered Chekanov-Eliashberg differential graded algebra by incorporating disks with multiple positive punctures into the differential.
