ABSTRACT=This study attempts to establish new upper bounds on the mean curvature and constant sectional curvature of the first positive eigenvalue of the ψ-Laplacian operator on Riemannian manifolds. Various approaches are being used to find the first eigenvalue for the ψ- Laplacian operator on closed oriented bi-slant submanifolds in a Sasakian space form. We extend different Reilly-like inequalities to the $\psi-$Laplacian on bi-slant submanifolds in a unit sphere depending on our results for the Laplacian. The conclusion of this study considers some special cases as well.
