The symmetric quantum calculus is studied, namely the $\\alpha,\\beta$-symmetric, the $q$-symmetric, and the Hahn symmetric quantum calculus. We introduce the symmetric quantum variational calculus and an Euler-Lagrange type equation for the $q$-symmetric and Hahn's symmetric quantum calculus is proved. We define a symmetric derivative on time scales and derive some of its properties. Finally, we introduce and study the diamond integral, which is a refined version of the diamond-$\\alpha$ integral on time scales.", "revisions": [ { "version": "v1", "updated": "2013-06-06T07:55:50.000Z" } ], "analyses": { "subjects": [ "34N05", "39A12", "39A13", "49K05", "49K15" ], "keywords": [ "time scales", "hahn symmetric quantum calculus", "hahns symmetric quantum calculus", "symmetric quantum variational calculus", "hahn variational calculus" ], "tags": [ "dissertation", "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2013arXiv1306.1327B" } } }
