New eigenvalue estimates involving Bessel functions
Fida El Chami, Nicolas Ginoux, Georges Habib
Given a compact Riemannian manifold (M n , g) with boundary M , we give an estimate for the quotient M f d g M f d g , where f is a smooth positive functi…

Fida El Chami, George Habib, Ola Makhoul +1
In [4], we gave a sharp lower bound for the first eigenvalue of the basic Laplacian acting on basic -forms defined on a compact manifold whose boundary is endowed with a Riemann…
