Fourier analysis provides a powerful framework for decomposing functions into sums or integrals of sinusoidal components, thereby enabling the study of frequency content in signals. In tandem, ...

Every composition operator Cφ on the Lipschitz space Lip0(X) attains its norm. This fact is essentially known and we give in this paper a sequential characterization of the extremal functions for the ...
