On behalf of the local organizing committee it is my pleasure to invite you to come to Marseille at the end of July, 2017 (24-28 July 2017). We are planning now to prepare a great Congress, and one as good as the previous Congress in Vigo Spain. We can now inform you that the registration costs will be the same as those in Vigo, so the 8th World Congress will not be expensive. We are currently planning the venue for the main meeting and receptions.
Informations about the congress are avalaible here: https://wca2017.sciencesconf.org/
