These functions, subjected to the requirement to be completely monotone for $t>0$, are shown to be suitable models for non--Debye relaxation phenomena in dielectrics including as particular cases the classical models referred to as Cole-Cole, Davidson-Cole and Havriliak-Negami. We show 3D plots of the response functions and of the corresponding spectral distributions, keeping fixed one of the three order-parameters.", "revisions": [ { "version": "v2", "updated": "2014-02-13T08:45:34.000Z" } ], "analyses": { "subjects": [ "26A33", "33E12", "44A10" ], "keywords": [ "mittag-leffler functions", "anomalous relaxation", "dielectrics", "laplace transform pairs", "complete monotonicty properties" ], "tags": [ "journal article" ], "publication": { "doi": "10.1140/epjst/e2011-01388-0", "journal": "European Physical Journal Special Topics", "year": 2011, "month": "Mar", "volume": 193, "pages": 161 }, "note": { "typesetting": "TeX", "pages": 22, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011EPJST.193..161C" } } }
