From the potential to the first Hochschild cohomology group of a cluster tilted algebra
Abstract
The objective of this paper is to give a concrete interpretation of the dimension of the first Hochschild cohomology space of a cyclically oriented or tame cluster tilted algebra in terms of a numerical invariant arising from the potential.
