Augmentations, Fillings, and Clusters
@article{Gao2020AugmentationsFA, title={Augmentations, Fillings, and Clusters}, author={Honghao Gao and Li-Chien Shen and Daping Weng}, journal={arXiv: Symplectic Geometry}, year={2020} }
We prove that the augmentation variety of any positive braid Legendrian link carries a natural cluster $\mathrm{K}_2$ structure. We present an algorithm to calculate the cluster seeds that correspond to the admissible Lagrangian fillings of the positive braid Legendrian links. Utilizing augmentations and cluster algebras, we develop a new framework to distinguish exact Lagrangian fillings.
