Speaker: Joris Roos (University of Massachusetts, Lowell)Title: A fractal local smoothing problem for the wave equationAbstract: We will talk about a variant of the well-known local smooth- ing conjecture with times restricted to a fractal set. The frac- tal conjecture involves a new dimensional spectrum called the Legendre-Assouad function, which also comes up in the char- acterization of 𝐿𝑝-improving properties of spherical maximal functions. Joint work with David Beltran, Alex Rutar and An- dreas Seeger.

Citizenfour (2014), 114 minutes. Laura Poitras (director)Introduction by Mariel Garcia-Montes (HASTS) and Michelle Spektor (SERC)Topic: Government overreach, Surveillance, AuthoritarianismCitizenfour gives audiences an exclusive front-row seat to the moment Edward Snowden changed history with his revelations of widespread government surveillance around the world. In June 2013, filmmaker Laura Poitras and journalist Glenn Greenwald met with Snowden confidentially in Hong Kong, where he handed over classified documents providing evidence of mass indiscriminate and illegal invasions of privacy by the National Security Agency (NSA). As the story breaks, they are forced to manage the raging media storm around them, and find their personal security and that of their loved ones under threat.Cinema at the Nexus is an institute-wide film series which showcases films/documentaries that grapple with pressing issues of our day aiming to make sense of what we are experiencing today.Other events in the series:Cinema at the Nexus: "The Cost of AI" | Introduction by Eric Robsky Huntley, October 27Cinema at the Nexus: Prisoner No. 626710 is Present | Introduction by Sana Aiyar, November 13Supported by the SHASS Dean’s grant, hosted by the MIT Libraries.Pizza and light refreshments will be served.Contact for suggestions and questions: doylec@mit.edu, szarko@mit.edu, turnator@mit.edu
