METALLIC RIEMANNIAN SPACE FORMS

Abstract

In this study we examine the cases of constant sectional curvature in Metallic Riemannian manifolds. We show that classical and holomorphic-like curvatures generally make the manifold at. Based on this, we introduce a new concept called Metallic sectional curvature, and in this setting, we derive the explicit expression of the curvature tensor. In addition, the Ricci tensor and scalar curvature are computed, and the conditions under which the manifold is Einstein are discussed. Finally, this new curvature notion is applied to semi-invariant and totally umbilical submanifolds, yielding rich geometric results.
