Ricci curvature for biwarped product submanifolds of the type N𝜃1 ×f2N𝜃2 ×f3N𝜃3 in Kenmotsu space forms

Abstract

The major goal of this work is to express the Ricci curvature inequality for biwarped product submanifold of the type [Formula: see text] isometrically immersed in a Kenmotsu space form via terms of the squared norm of mean curvature vector and warping functions, where [Formula: see text], [Formula: see text] and [Formula: see text] are the slant submanifolds with slant angles [Formula: see text], [Formula: see text] and [Formula: see text]. The interpretations of equality are also explored. In addition, we provide several applications of these inequalities.
