3rd Announcement of BWB 2018 Second Brazilian Workshop in Geometry of Banach Spaces August 13-17, 2018 Praia das Toninhas, Ubatuba, Sao Paulo State, Brazil. (Satellite Conference of the ICM 2018) We would like to remind you that we are organizing the Second Brazilian Workshop in Geometry of Banach Spaces BWB 2018, as a satellite conference of the ICM 2018. *Registration and abstract submission are now open and the deadline is May 15.* https://www.ime.usp.br/~banach/bwb2018/ The BWB will take place at the Wembley Inn Hotel, on the coast of Sao Paulo State, in Praia das Toninhas, Ubatuba, in the week August 13-17, 2018. The scientific program will focus on the theory of geometry of Banach spaces, with emphasis on the following directions: large scale geometry of Banach spaces; nonlinear theory; homological theory and set theory. The program includes a tutorial by Christian Rosendal, which will be accessible to graduate students. Additional scientific, practical and financial information can be found on website https://www.ime.usp.br/~banach/bwb2018/. Plenary speakers: S. A. Argyros (Nat. Tech. U. Athens) G.
