After establishing the correspondence between (rational) nodal curves on $S-Y$ and Riccati solutions, we give the complete classification of the configurations of nodal curves on $S-Y$ for each Okamoto-Painlev\\'e pair $(S, Y)$. As an application of the classification, we prove the non-existence of Riccati solutions of Painlev\\'e equations of types $P_{I}, P_{III}^{\\tilde{D}_8}$ and $P_{III}^{\\tilde{D}_7}$. We will also give a partial answer to the conjecture in (STT) and (T) that the dimension of the local cohomology $H^1_{Y_{red}}(S,\\Theta_S(-\\log Y_{red}))$ is one.", "revisions": [ { "version": "v1", "updated": "2002-01-23T16:37:34.000Z" } ], "analyses": { "subjects": [ "14D15", "34M55", "32G10" ], "keywords": [ "nodal curves", "painleve equations", "okamoto-painleve pair", "study riccati solutions", "view point" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 30, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2002math......1225S" } } }
