In the present paper, we extend this study to put light on the curvature properties of such submersions and then obtain optimal inequalities for Riemannian warped product submersions involving vertical Casorati curvatures. Also, we discuss under which conditions the equality case of inequality can hold with an example.eninfo:eu-repo/semantics/closedAccessRiemannian immersionRiemannian submersionwarped productvertical Casorati curvaturesEinstein manifoldArticle10.1007/s00009-023-02313-5202WOS:0009262275000012-s2.0-85147416040Q1Q2
