“…In this contribution, we shall define a new useful operator denoted by δ k e 1 e 2 for which we can formulate, extend and prove new results based on our previous ones, see [16], [3], [18]. In order to determine generating functions of product of k-Fibonacci, k-Lucas, k-Pell, k-Jacobsthal and Mersenne numbers with Tribonacci and Tribonacci Lucas polynomials, we combine between our indicated past techniques and these presented polishing approaches.…”
