Abstract

In this paper, we give a neutral relation between metallic structure and almost quadratic metric phi-structure. Considering N as a metallic Riemannian manifold, we show that the warped product manifold Rx(f) N has an almost quadratic metric phi-structure. We define Kenmotsu quadratic metric manifolds, which include cosymplectic quadratic manifolds when beta = 0. Then we give nice almost quadratic metric phi-structure examples. In the last section, we construct a quadratic phi-structure on the hypersurface M-n of a locally metallic Riemannian manifold (M) over tilde (n+1).
