# nLab quiver with potential

Given a quiver $Q$, a potential for $Q$ is a cyclically invariant element in its path algebra or its completion. Cyclic invariance means that it is a linear combination of cyclic paths; cyclic invariance can be in a ${\mathbf Z}_2$-graded sense in which case it is called a superpotential. This is in agreement with another notion of a superpotential in Donaldson-Thomas theory. The space of superpotentials has a necklace Lie algebra structure.
