Quiver algebras and their representations for arbitrary quivers
Journal of High Energy PhysicsThe quiver Yangians were originally defined for the quiver and superpotential from string theory on general toric Calabi-Yau threefolds, and serve as BPS algebras of these systems.

The combinatorics of quiver representations [PDF]
Annales de l'Institut Fourier, 2011 We give a description of faces, of all codimensions, for the cones spanned by the set of weights associated to the rings of semi-invariants of quivers. For a triple flag quiver and its faces of codimension 1 this description reduces to the result of Knutson-Tao-Woodward on the facets of the Klyachko cone.

Representations of thread quivers [PDF]
Proceedings of the London Mathematical Society, 2013 We introduce thread quivers as an (infinite) generalization of quivers, and show that every k-linear (k algebraically closed) hereditary category with Serre duality and enough projectives is equivalent to the category of finitely presented representations of a thread quiver.

Learning scattering amplitudes by heart
Physics Letters B, 2021 The canonical forms associated to scattering amplitudes of planar Feynman diagrams are interpreted in terms of masses of projectives, defined as the modulus of their central charges, in the hearts of certain t-structures of derived categories of quiver ...

Desingularization of quiver Grassmannians for Dynkin quivers [PDF]
, 2013 A desingularization of arbitrary quiver Grassmannians for representations of Dynkin quivers is constructed in terms of quiver Grassmannians for an algebra derived equivalent to the Auslander algebra of the quiver.Comment: 22 pages; typos corrected ...

MPS degeneration formula for quiver moduli and refined GW/Kronecker correspondence [PDF]
, 2011 Motivated by string-theoretic arguments Manschot, Pioline and Sen discovered a new remarkable formula for the Poincare polynomial of a smooth compact moduli space of stable quiver representations which effectively reduces to the abelian case (i.e.

Quiver Grassmannians associated with string modules [PDF]
, 2010 We provide a technique to compute the Euler characteristic of a class of projective varieties called quiver Grassmannians. This technique applies to quiver Grassmannians associated with "orientable string modules". As an application we explicitly compute
