Earlier studies require that the operator involved is Fr\u00e9chet differentiable. In the present study we assume that the operator is only continuous. This way we extend the applicability of Newton-type methods to include fractional calculus and problems from other areas. Moreover, under the same or weaker conditions, we obtain weaker sufficient convergence criteria, tighter error bounds on the distances involved and an at least as precise information on the location of the solution. Special cases are provided where the old convergence criteria cannot apply but the new criteria can apply to locate zeros of operators. Some applications include fractional calculus involving the Riemann-Liouville fractional integral and the Caputo fractional derivative. Fractional calculus is very important for its applications in many applied sciences.<\/jats:p>","DOI":"10.3390\/a8040832","type":"journal-article","created":{"date-parts":[[2015,10,9]],"date-time":"2015-10-09T11:37:33Z","timestamp":1444390653000},"page":"832-849","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Newton-Type Methods on Generalized Banach Spaces and Applications in Fractional Calculus"],"prefix":"10.3390","volume":"8","author":[{"given":"George","family":"Anastassiou","sequence":"first","affiliation":[{"name":"Department of Mathematical Sciences, University of Memphis, Memphis, TN 38152, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9189-9298","authenticated-orcid":false,"given":"Ioannis","family":"Argyros","sequence":"additional","affiliation":[{"name":"Department of Mathematics Sciences, Cameron University, Lawton, OK 73505, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2015,10,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"243","DOI":"10.1016\/j.jmaa.2007.02.052","article-title":"Third-order iterative methods under Kantorovich conditions","volume":"336","author":"Amat","year":"2007","journal-title":"J.
