One of the events already took place last February: the LxDS Workshop on New trends in Lyapunov exponents.
The other event will take place next July: the Portugal-Italy Conference on Nonlinear Differential Equations and Applications (PICNDEA22).
Both will have their proceedings published in the CIM Series in Mathematical Sciences published by Springer.
