Characterization of Lipschitz functions in terms of variable exponent Lebesgue spaces
Pu Zhang
Our aim is to characterize the Lipschitz functions by variable exponent Lebesgue spaces. We give some characterizations of the boundedness of the maximal or nonlinear commutators o…

Characterization of Lipschitz spaces via commutators of the Hardy-Littlewood maximal function
Pu Zhang
Let be the Hardy-Littlewood maximal function and be a locally integrable function. Denote by and the maximal commutator and the (nonlinear) commutator of …
