We present the first examples of elements in the fundamental group of the space of Legendrian links in (S, ξst) whose action on the Legendrian contact DGA is of infinite order. This allows us to construct the first families of Legendrian links that can be shown to admit infinitely many Lagrangian fillings by Floer-theoretic techniques. These families include the first known Legendrian links with infinitely many fillings that are not rainbow closures of positive braids, and the smallest…

Given an immersed, Maslov-0, exact Lagrangian filling of a Legendrian knot, if the filling has a vanishing index and action double point, then through Lagrangian surgery it is possible to obtain a

We continue the study of exact Lagrangian fillings of Legendrian (2, n) torus links, as first initiated by Ekholm-Honda-Kalman and Pan. Our main result proves that for a decomposable exact Lagrangian

We establish new examples of augmentations of Legendrian twist knots that cannot be induced by orientable Lagrangian fillings. To do so, we use a version of the Seidel –Ekholm–Dimitroglou Rizell

We study exact Lagrangian fillings of Legendrian links of Dn-type in the standard contact 3-sphere. The main result is the existence of a Lagrangian filling, represented by a weave, such that any
