well as for Steklov problems on submanifolds of Riemannian manifolds of bounded
sectional curvature endowed with a weighted measure. … The first result of this paper gives
upper bounds for the first eigenvalue of the operator \(L_{T,f}\) for submanifolds of
Riemannian manifolds with sectional curvature bounded by above which generalizes
inequality (7) in the non-constant curvature case. Namely, we prove the following. … The …
