That is, we show that intersection numbers on the moduli space of stable r-spin curves assemble into a generating function which yields a solution of the semiclassical limit of the KdV_r equations. We formulate axioms for a cohomology class on this moduli space which allow one to construct a cohomological field theory of rank $r-1$ in all genera. In genus zero it produces a Frobenius manifold which is isomorphic to the Frobenius manifold structure on the base of the versal deformation of the A_{r-1} singularity. We prove analogs of the puncture, dilaton, and topological recursion relations by drawing an analogy with the construction of Gromov-Witten invariants and quantum cohomology.", "revisions": [ { "version": "v4", "updated": "2000-02-09T18:30:36.000Z" } ], "analyses": { "subjects": [ "14H10", "32G15", "81T40" ], "keywords": [ "higher spin curves", "integrable hierarchies", "witten conjecture relating moduli spaces", "frobenius manifold structure", "genus zero part" ], "tags": [ "journal article" ], "note": { "typesetting": "LaTeX", "pages": 65, "language": "en", "license": "arXiv", "status": "editable", "inspire": 499908, "adsabs": "1999math......5034J" } } }
