Essential Norm of Composition Operators on Banach Spaces of Hölder Functions

Let (X,d) be a pointed compact metric space, let 0<α<1, and let φ:X→X be a base point preserving Lipschitz map. We prove that the essential norm of the composition operator Cφ induced by the symbol φ on the spaces lip0(X,dα) and Lip0(X,dα) is given by the formula ‖Cφ‖e=limt→0 sup⁡0<d(x, y)&...
