We introduce Bernstein-type operators based in the weighted classical Jacobi inner product on the interval [0,\u00a01] that extend the well known Bernstein\u2013Durrmeyer operator as well as some other types of Bernstein operators that appear in the literature. Apart from standard results, we deduce properties about the preservation of derivatives and prove that classical Jacobi orthogonal polynomials on [0,\u00a01] are the eigenfunctions of these operators. We also study the limit cases when one of the parameters of the Jacobi polynomials is a negative integer. Finally, we study several numerical examples.<\/jats:p>","DOI":"10.1007\/s40314-024-02796-2","type":"journal-article","created":{"date-parts":[[2024,6,12]],"date-time":"2024-06-12T07:01:41Z","timestamp":1718175701000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Bernstein\u2013Jacobi-type operators preserving derivatives"],"prefix":"10.1007","volume":"43","author":[{"given":"David","family":"Lara-Velasco","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0889-6484","authenticated-orcid":false,"given":"Teresa E.","family":"P\u00e9rez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2024,6,12]]},"reference":[{"key":"2796_CR1","volume-title":"Handbook of mathematical functions, with formulas, graphs, and mathematical tables","author":"M Abramowitz","year":"1972","unstructured":"Abramowitz M, Stegun IA (1972) Handbook of mathematical functions, with formulas, graphs, and mathematical tables.
