This is an announcement for the paper “Rademacher type and Enflo type coincide” by Paata Ivanisvili<https://arxiv.org/search/math?searchtype=author&query=Ivanisvili%2C+P>, Ramon van Handel<https://arxiv.org/search/math?searchtype=author&query=van+Handel%2C+R>, Alexander Volberg<https://arxiv.org/search/math?searchtype=author&query=Volberg%2C+A>. Abstract: A nonlinear analogue of the Rademacher type of a Banach space was introduced in classical work of Enflo. 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. The paper may be downloaded from the archive by web browser from URL https://arxiv.org/abs/2003.06345
