Prolongations of Golden Structure to Tangent Bundle of Order 2

In this paper, we study 2 nd lift of golden structure to tangent bundle of order 2. We investigate integrability and parallelism of Gloden structures in $T_2insert ignore into journalissuearticles values(M);$. Moreover, we define golden semi-Riemannian metric in $T_2insert ignore into journalissuearticles values(M);$.
