Query: Cheeger's constant and the first eigenvalue of a closed Finsler manifold   In this paper, we consider Cheeger's constant and the first eigenvalue of the
nonlinear Laplacian on closed Finsler manifolds. Being based on these, we
establish Cheeger's inequality and Buser's inequality for closed Finsler
manifolds.
