On the properties of circulant matrices involving Generalized Tribonacci   and Generalized Tribonacci-Lucas numbers
  In this paper, firstly, we define the Generalized Tribonacci-Lucas numbers. In addition, by also defining circulant matrices C_{n}(G) and C_{n}(S) whose entries are Generalized Tribonacci and Generalized Tribonacci-Lucas numbers, we compute spectral norms and determinants of these matrices.
