The complexity of\nsolutions generally grow exponentially in the particle number\, so for\nlarge N coarse-graine d or effective descriptions are desirable. From a\nmathematical physics po int of view\, one aims at deriving effective\nequations in a rigorous way\ , i.e.\, proving that their solutions converge\nto the solutions of the Sc hroedinger equation in a suitable topology. In\nthis talk\, we will consid er the dynamics in the mean-field limit\, which\nhas been studied extensiv ely in the last two decades. I will present an\noverview about the researc h goals and results\, and then specifically\ndiscuss recent results of my collaborators and myself on a perturbative\nexpansion of solutions to the Schroedinger equation.\n LOCATION:https://researchseminars.org/talk/BODS/5/ END:VEVENT END:VCALENDAR
