Dear Friends, this is the second announcement of the workshop "A journey through complex systems: from interacting particles to games" which will take place in L'Aquila on September 21-24, 2022. The workshop is planned as a hybrid event with on-site participation. The workshop will celebrate the 60th birthday of Paolo Dai Pra through a series of talks that will cover the spectrum of research lines to which Paolo has contributed to. The covered topics include: complex systems in biological and social sciences, geometric and scaling properties of stochastic processes, convergence to equilibrium and functional inequalities for interacting particle systems, mean-field games and stochastic control. Participation is free of charge but, for organizational reasons, registration is mandatory both for in-person and remote participation. * If you wish to participate in-person, we kindly ask you to register by July 31, 2022. The capacity of the conference room is limited and will be allocated on a "first come first serve" basis. * There is no deadline to register for online participation. More information about the workshop venue and program, about registration and about travel and accommodation are available on the website https://sites.google.com/view/pdp60laquila. We look forward to seeing you in L'Aquila! Best regards, The Organizing Committee Francesca Collet, Marco Formentin, Pierre-Yves Louis, Ida Germana Minelli, Elena Sartori, Marco Tolotti
