Quiver diagram

Quiver diagram

In physics, a quiver diagram is a graph representing the matter content of a gauge theory that describes D-branes on orbifolds.

Each node of the graph corresponds to a factor U(N) of the gauge group, and each link represents a field in the bifundamental representation

(M,\bar{N}).

The relevance of quiver diagrams for string theory was pointed out and studied by Michael Douglas and Greg Moore.[1]

While string theorists use the words quiver diagram, many of their colleagues in particle physics call these diagrams mooses.
