We give a review of the quantum singularity theory of Fan-Jarvis-Ruan and the r-spin theory of Jarvis-Kimura-Vaintrob and describe the work of Abramovich-Jarvis showing that for the singularity Ar-1 = xr the stack of Ar-1-curves of is canonically isomorphic to the stack of r-spin curves. We prove that the Ar-1-theory satisfies all the axioms of Jarvis-Kimura-Vaintrob for an r-spin virtual class. Therefore, the results of Lee, Faber-Shadrin-Zovonkine, and Givental all apply to the Ar-1-theory. In particular, this shows that the Witten Integrable Hierarchies Conjecture is true for the Ar-1-theory; that is, the total descendant potential function of the Ar-1-theory satisfies the r-th Gelfand-Dikii hierarchy.
