As a corollary, we also determine all Lucas numbers close to a power of 2. The main tools used in this work are lower bounds for linear forms in logarithms due to Matveev and Dujella-Peth\\\"{o} version of the Baker-Davenport reduction method in diophantine approximation. This paper continues and extends the previous work of Chern and Cui.", "revisions": [ { "version": "v1", "updated": "2022-06-14T20:44:14.000Z" } ], "analyses": { "subjects": [ "11B39", "11J86" ], "keywords": [ "fibonacci numbers close", "lucas numbers close", "baker-davenport reduction method", "lower bounds", "linear forms" ], "note": { "typesetting": "TeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable" } } }
