A reformulation of this result for sesquilinear maps with a geometric mean closed semiprime Archimedean (real or complex) $f$-algebra as codomain is also given. In addition, a sufficient and necessary condition for equality is presented. We also prove the H\\\"older inequality for weighted geometric mean closed Archimedean (real or complex) $\\Phi$-algebras, improving results by Boulabiar and Toumi. As a consequence, the Minkowski inequality for weighted geometric mean closed Archimedean (real or complex) $\\Phi$-algebras is obtained.", "revisions": [ { "version": "v1", "updated": "2016-07-22T11:48:21.000Z" } ], "analyses": { "keywords": [ "inequality", "vector lattice", "weighted geometric mean closed archimedean", "classical inequalities", "sesquilinear maps" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
