Sparse Days Meeting 2019 at Cerfacs, Toulouse

Brigitte Yzel |  12 May 2019

The annual Sparse Days meeting will be held at CERFACS in Toulouse on 11th and 12th July 2019. Registration for the Sparse Days is free but we ask people who are coming to register as soon as possible although the deadline is June 14th. Please complete the registration form (deadline : June 14th) indicating whether you want to give a talk and whether you wish to attend the conference dinner. Although an emphasis will be on parallel aspects, any talk that has an association with sparsity is welcome.Read more
