The key feature of Enflo type is that its definition uses only the metric structure of the Banach space, while the definition of Rademacher type relies on its linear structure. We prove that Rademacher type and Enflo type coincide, settling a long-standing open problem in Banach space theory. The proof is based on a novel dimension-free analogue of Pisier's inequality on the discrete cube.}, number={2}, journal={ANNALS OF MATHEMATICS}, author={Ivanisvili, Paata and Handel, Ramon and Volberg, Alexander}, year={2020}, month={Sep}, pages={665–678} }
