We analyze relations between BPS degeneracies related to Labastida-Mariño-Ooguri-Vafa (LMOV) invariants and algebraic curves associated to knots. We introduce a new class of such curves, which we call extremal A-polynomials, discuss their special properties, and determine exact and asymptotic formulas for the corresponding (extremal) BPS degeneracies. These formulas lead to nontrivial integrality statements in number theory, as well as to an improved integrality conjecture, which is stronger… 
BPS counting for knots and combinatorics on words
A bstractWe discuss relations between quantum BPS invariants defined in terms of a product decomposition of certain series, and difference equations (quantum A-polynomials) that annihilate such
Knots-quivers correspondence
We introduce and explore the relation between knot invariants and quiver representation theory, which follows from the identification of quiver quantum mechanics in D-brane systems representing
Donaldson-Thomas invariants, torus knots, and lattice paths
In this paper, we find and explore the correspondence between quivers, torus knots, and combinatorics of counting paths. Our first result pertains to quiver representation theory—we find explicit
Checks of integrality properties in topological strings
A bstractTests of the integrality properties of a scalar operator in topological strings on a resolved conifold background or orientifold of conifold backgrounds have been performed for arborescent
Topological strings, strips and quivers
A bstractWe find a direct relation between quiver representation theory and open topological string theory on a class of toric Calabi-Yau manifolds without compact four-cycles, also referred to as
Nahm sums, quiver A-polynomials and topological recursion
Abstract We consider a large class of q-series that have the structure of Nahm sums, or equivalently motivic generating series for quivers. First, we initiate a systematic analysis and
On explicit formulae of LMOV invariants
Abstract We started a program to study the open string integrality invariants (LMOV invariants) for toric Calabi-Yau 3-folds with Aganagic-Vafa brane (AV-brane) several years ago. This paper is
Refined large N duality for knots
We formulate large $N$ duality of $\mathrm{U}(N)$ refined Chern-Simons theory with a torus knot/link in $S^3$. By studying refined BPS states in M-theory, we provide the explicit form of low-energy


Polynomial Invariants for Torus Knots¶and Topological Strings
Abstract: We make a precision test of a recently proposed conjecture relating Chern–Simons gauge theory to topological string theory on the resolution of the conifold. First, we develop a systematic
Homological algebra of knots and BPS states
It is known that knot homologies admit a physical description as spaces of open BPS states. We study operators and algebras acting on these spaces. This leads to a very rich story, which involves
Knot Invariants from Topological Recursion on Augmentation Varieties
Using the duality between Wilson loop expectation values of SU(N) Chern–Simons theory on S3 and topological open-string amplitudes on the local mirror of the resolved conifold, we study knots on S3
Quadruply-graded colored homology of knots
We conjecture the existence of four independent gradings in colored HOMFLYPT homology, and make qualitative predictions of various interesting structures and symmetries in the colored homology of
3d analogs of Argyres-Douglas theories and knot homologies
A bstractWe study singularities of algebraic curves associated with 3d $ \mathcal{N}=2 $ theories that have at least one global flavor symmetry. Of particular interest is a class of theories TK
Super-A-polynomials for twist knots
A bstractWe conjecture formulae of the colored superpolynomials for a class of twist knots Kp where p denotes the number of full twists. The validity of the formulae is checked by applying
Large N Duality, Lagrangian Cycles, and Algebraic Knots
We consider knot invariants in the context of large N transitions of topological strings. In particular we consider aspects of Lagrangian cycles associated to knots in the conifold geometry. We show
Torus Knots and the Topological Vertex
We propose a class of toric Lagrangian A-branes on the resolved conifold that is suitable to describe torus knots on S3. The key role is played by the $${SL(2, \mathbb{Z})}$$SL(2,Z) transformation,
