Bounds for the first Dirichlet eigenvalue attained at an infinite family of Riemannian manifolds
Let \(M\) be a compact Riemannian manifold with smooth boundary \(\partial M\). The authors get bounds for the first eigenvalue of the Dirichlet eigenvalue problem on \(M\) in terms of bounds of the sectional curvature of \(M\) and the normal curvature of \(\partial M\). Similar results hold for Kähler manifolds.
