Abstract
Let M be a finitely generated module over an Artin algebra A. The Auslander–Reiten conjecture says that if \({{\rm Ext}^n_A(M, M \oplus A) = 0}\) for all natural numbers n, then M is projective. In the paper, we prove that the conjecture is true for all symmetric special biserial algebras and that it is also true for special biserial algebras with radical cube zero.
