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. 

Non-fillable Augmentations of Twist Knots

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

Lagrangian cobordism of positroid links

Casals-Gorsky-Gorsky-Simental realized all positroid strata of the complex Grassmannian as augmentation varieties of Legendrians called positroid links. We prove that the partial order on strata

Positive Braid Links with Infinitely Many Fillings

We prove that any positive braid Legendrian link not isotopic to a standard finite type link admits infinitely many exact Lagrangian fillings.

ON TOPOLOGICALLY DISTINCT INFINITE FAMILIES OF EXACT LAGRANGIAN FILLINGS

. In this note we construct examples of closed connected Legendrian submanifolds in high dimensional contact vector space that admit an arbitrary finite number of topologically distinct infinite

DT Transformation and Infinitely Many Fillings

We prove that any positive braid Legendrian link not isotopic to a standard finite type link admits infinitely many exact Lagrangian fillings.

Augmented Legendrian cobordism in $J^1S^1$

We consider Legendrian links and tangles in JS and J[0, 1] equipped with Morse complex families over a field F and classify them up to Legendrian cobordism. When the coefficient field is F2 this

Algebraic Weaves and Braid Varieties

In this manuscript we study braid varieties, a class of affine algebraic varieties associated to positive braids. Several geometric constructions are presented, including certain torus actions on

. In this short note we discuss high-dimensional examples of Legendrian submanifolds of the standard contact Euclidean space with an infinite number of exact Lagrangian fillings up to Hamiltonian

LAGRANGIAN SKELETA AND PLANE CURVE SINGULARITIES

We construct closed arboreal Lagrangian skeleta associated to links of isolated plane curve singularities. This yields closed Lagrangian skeleta for Weinstein pairs (C,Λ) and Weinstein 4-manifolds W

Infinitely many planar fillings and symplectic Milnor fibers

We provide a new family of Legendrian links with infinitely many distinct exact orientable Lagrangian fillings up to Hamiltonian isotopy. This family of links includes the first examples of

Braid-positive Legendrian links

Any link that is the closure of a positive braid has a natural Legendrian representative. These were introduced in [15], where their Chekanov– Eliashberg contact homology was also evaluated. In this

Exact Lagrangian Fillings of Legendrian $(2,n)$ torus links

For a Legendrian $(2,n)$ torus knot or link with maximal Thurston-Bennequin number, Ekholm, Honda, and K\'alm\'an constructed $C_n$ exact Lagrangian fillings, where $C_n$ is the $n$-th Catalan

Positive Braid Links with Infinitely Many Fillings

We prove that any positive braid Legendrian link not isotopic to a standard finite type link admits infinitely many exact Lagrangian fillings.

On tropical dualities in cluster algebras

We study two families of integer vectors playing a crucial part in the structural theory of cluster algebras: the $\gg$-vectors parameterizing cluster variables, and the $\cc$-vectors parameterizing

Augmentations are sheaves

We show that the set of augmentations of the Chekanov-Eliashberg algebra of a Legendrian link underlies the structure of a unital A-infinity category. This differs from the non-unital category

Augmentations and rulings of Legendrian knots

A connection between holomorphic and generating family invariants of Legendrian knots is established; namely, that the existence of a ruling (or decomposition) of a Legendrian knot is equivalent to

Generating families and Legendrian contact homology in the standard contact space

We show that if a Legendrian knot in a standard contact space ℝ3 possesses a generating family, then there exists an augmentation of the Chekanov–Eliashberg differential graded algebra so that the
