Data e ora: Martedì 22 Novembre, ore 14:00 Luogo: Sala di Consiglio, Dipartimento di Matematica, Sapienza Università di Roma Speaker: Mauro Mariani Titolo: Long time asymptotic of action functionals Abstract: I will provide a self-contained variational approach to state some classical and new results in the framework of Aubry-Mather theory. More precisely, I will discuss the expansion by Gamma-convergence of the action functional of classical mechanics, as the time-scale diverges. Joint work with Carlo Orrieri.
