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).eninfo:eu-repo/semantics/closedAccessFibonacci NumberLucas NumberFibonacci MatrixLucas MatrixPascal MatrixArticle43A5244324482-s2.0-85073235296Q2WOS:000487075500041Q310.1007/s40995-019-00715-3
