Abstract
Halici (Adv Appl Clifford Algebr 25(4):905–914, 2015) defined dual Fibonacci and dual Lucas octonions by the relations \({\widetilde{Q}_{n}={Q}_n+\varepsilon Q_{n+1}}\) and \({\widetilde{P}_n=P_n+\varepsilon P_{n+1}}\) for every integer n where \({Q_n}\) and \({P_n}\) are the Fibonacci and Lucas octonions respectively, and \({\varepsilon}\) is the dual unit. The aim of this paper is to investigate properties of dual Fibonacci and dual Lucas octonions. After obtaining the Binet formulas for the sequences \({\{\widetilde{Q}_n \}_{n=0}^\infty}\) and \({\{\widetilde{P}_n \}_{n=0}^\infty}\), we derive some identities for these sequences such as Catalan’s, Cassini’s and d’Ocagne’s identities.
