Quiver Structure of Heterotic Moduli

Understand

We analyse the vector bundle moduli arising from generic heterotic compactifications from the point of view of quiver representations.

• Phenomena such as stability walls, crossing between chambers of supersymmetry, splitting of non-Abelian bundles and dynamic generation of D-terms are succinctly encoded into finite quivers.
• By studying the Poincar\'e polynomial of the quiver moduli space using the Reineke formula, we can learn about such useful concepts as Donaldson-Thomas invariants, instanton transitions and supersymmetry breaking.
