Abstract. Some classical nonlinear semigroups arising in mechanics induce unilateral bounds on solutions. Hamilton-Jacobi equations and 1-d scalar conservation laws are classical examples of such nonlinear effects: solutions spontaneously develop one-sided Lipschitz or semi-concavity conditions. When this occurs the range of the semigroup is unilaterally bounded by a threshold. On the other hand, in practical applications, one is often led to consider the problem of time-inversion, so to identify the initial sources that originated the observed dynamics at the final time.
In this lecture we shall discuss this problem and address the following specific questions:
-Identification of the range of the semigroup
-Identification of the class of initial data leading to a target
-Least-square approaches versus backward-forward resolution.
-Numerical reconstruction.
We shall also present a number of open problems arising in this area and the possible link with reinforcement learning.
