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 $\mathbb {R}\times _ {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 …

In this paper, we give a neutral relation between metallic structure and almost quadratic
metric ϕ-structure. Considering N as a metallic Riemannian manifold, we show that the
warped product manifold R× f N has an almost quadratic metric ϕ-structure. We define
Kenmotsu quadratic metric manifolds, which include cosymplectic quadratic manifolds when
β= 0. Then we give nice almost quadratic metric ϕ-structure examples. In the last section, we
construct a quadratic ϕ-structure on the hypersurface Mn of a locally metallic Riemannian …
