Sharp Cheeger–Buser Type Inequalities in [Formula: see text] Spaces
The goal of the paper is to sharpen and generalise bounds involving Cheeger’s isoperimetric constant h and the first eigenvalue [Formula: see text] of the Laplacian. A celebrated lower bound of [Formula: see text] in terms of h, [Formula: see text] , was proved by Cheeger in 1970 for smooth Riemanni...
