SUMMARY:Unilateral bounds for nonlinear semigroups and time-inversion by E. Zuazua
DESCRIPTION:On March 8th, our Head Enrique Zuazua will be talking on the ‘Geometric and functional inequalities and applications’ Seminar Series about: Unilateral bounds for nonlinear semigroups and time-inversion\nAbstract. 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 led to consider the problem of time-inversion, so to identify the initial sources that have led to the observed dynamics at the final time.\nIn this lecture we shall discuss this problem answering to the following two questions: On one hand, to identify the range of the semigroup and, given a target, to characterize and reconstruct the ensemble of initial data leading to it. Illustrative numerical simulations will be presented, and a complete geometric interpretation will also be provided. We shall also present a number of open problems arising in this area and the possible link with reinforcement learning.\nTO ATTEND TO THIS TALK\nWHEN?\nMarch 8th, 2021 at 15:00H (GMT Central European time)\nWHERE?\nRequest the Zoom link to geometricinequalitiesandpdes@gmail.com\nSee more at this Weekly Seminar series page\n
