Abstract: | In this paper, we characterize all the finite dimensional algebras that are derived equivalent to an m?cluster tilted algebra of type $mathbb{A}$ . These algebras are gentle, and we show that the derived class of such an algebra is completely determined by the rank of its Grothendieck group and the dimension of its first Hochschild cohomology group. |
