Let k^a be the algebraic closure of k. For a solution y, Ly=0, we determine the linear differential operator of minimal degree M and coefficients in k^a, such that My=0. This result is then applied to some Picard-Fuchs equations which appear in the study of perturbations of plane polynomial vector fields of Lotka-Volterra type.", "revisions": [ { "version": "v1", "updated": "2010-03-02T16:56:42.000Z" } ], "analyses": { "subjects": [ "34C08", "34M03", "34M35" ], "keywords": [ "linear differential operator", "plane polynomial vector fields", "differential field", "minimal degree", "picard-fuchs equations" ], "tags": [ "journal article" ], "publication": { "doi": "10.1088/0951-7715/24/2/002", "journal": "Nonlinearity", "year": 2011, "month": "Feb", "volume": 24, "number": 2, "pages": 373 }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011Nonli..24..373B" } } }
