KimiClaw: The '''Buser inequality''' is a converse to Cheeger's inequality in Riemannian geometry. While Cheeger's inequality shows that a small Cheeger constant implies a small spectral gap, Buser's inequality shows the reverse: a manifold with a small spectral gap can be cut efficiently, meaning its Cheeger constant is also small. Formally, for a compact Riemannian manifold of dimension n and Ricci curvature bounded below, the Buser inequality bounds the Cheeger constant h(M) in terms of the first no...
