 "Evolution of NLS with Bounded Data"

We study the nonlinear Schrodinger equation (NLS) with bounded initial data whichdoes not vanish at in finity. Examples include periodic, quasi-periodic and random initial data.On the lattice we prove that solutions are polynomially bounded in time for any bounded data. In the continuum, local existence is proved for real analytic data by a Newton iteration scheme. Global existence for NLS with a regularized nonlinearity follows by analyzing a local energy norm(arXiv:2003.08849 [math.AP]____________

How to hear the talk: A few minutes before the start of the talk, you will receive an email notification from SAKAI (from the sender "Rutgers University" with email address <>;)  and with the words [RU Math-Phys Seminar - New Meeting] in the title.  Following the link provided in that email should bring you to the seminar's SAKAI site, and the "Meetings" page of that site (you may be asked for your SAKAI userid and password in order to login first).  Alternatively, if you are already logged into SAKAI and are on the home page of this seminar's site, click on the "Meetings" tab on the left sidebar to go to the Meetings page.  Find and click on the button that invites you to join the conference in progress, and follow the directions you are given.  Please note that you may need to disable your browser's pop-up blocker.  You will be asked if you want to join with a microphone, or only listen.  If you'd like to be able to ask questions during the lecture, you may join with your mic. But please remember to mute your mic except for when you want to say something, in order to prevent echos.  You will be joining the conference as a "student" so you will not be able to share your webcam (this is to preserve bandwidth.)  Alternatively, you can type your questions in the "chat box" column to the left of your viewer.  You should be able to see and hear the speaker, and see their slides.  In addition to the speaker, a moderator will also be monitoring the chat box, and will be able to answer your technical questions.  Please note that the conference may be recorded, and the recording will include the chat as well.  

If you are experiencing difficulty joining the seminar that's in progress, please email who will send you a direct link
