From triangulated categories to Lie algebras: A theorem of Peng and Xiao
Andrew Hubery
We present a simplified and more intuitive proof of a theorem of Peng and Xiao, which constructs a Lie algebra from any 2-periodic triangulated k-category (satisfying some finitene…
The composition algebra of an affine quiver
Andrew Hubery
We study the Hall and composition algebras of an affine quiver. In the case of a cyclic quiver, we provide generators for the central polynomial algebra described by Schiffmann and…
The composition monoid and the composition algebra at q=0 of the Kronecker quiver
Andrew Hubery
We consider the Kronecker quiver and determine the relations for the specialisation to q=0 of the generic composition algebra as well as those for Reineke's composition monoid. We…
Quiver representations respecting a quiver automorphism: a generalisation of a theorem of Kac
Andrew Hubery
We consider quiver representations respecting a quiver automorphism and show that the dimension vectors of the indecomposables are precisely the positive roots of an associated sym…
