Abstract
In this study, a matrix \(R_{L}\) is defined by the properties associated with the Pascal matrix, and two closed-form expressions of the matrix function \(f(R_{L})=R_{L}^{n}\) are determined by methods in matrix theory. These expressions satisfy a connection between the integer sequences of the first–second kinds and the Pascal matrices. The matrix \(R_{L}^{n}\) is the Fibonacci Lucas matrix, whose entries are the Fibonacci and Lucas numbers. Also, the representations of the Lucas matrix are derived by the matrix function \(f(R_{L}-5I)\), and various forms of the matrix \((R_{L}-5I)^{n}\) in terms of a binomial coefficient are studied by methods in number theory. These representations give varied ways to obtain the new Fibonacci- and Lucas-type identities via several properties of the matrices \(R_{L}^{n}\) and \((R_{L}-5I)^{n}\).
