Title: Supergravity in a Brilliant Disguise Speaker: Tomasz Taylor Date: Friday, December 6, 2013 Time: 11:00am – 12:30pm Place: Seminar Room 313, Simons Center     [box, type=”download”]Watch the video.[/box] Abstract: Over the last decade, there has been enormous progress in understanding the structure of scattering amplitudes in gauge theories. It is less known that some significant […]

Title: Yangian Symmetry of smooth Wilson Loops in N=4 SYM Speaker: Jan Plefka Date: Thursday, December 5, 2013 Time: 11:00am – 12:30pm Place: Lecture Hall 102, Simons Center       [box, type=”download”]Watch the video.[/box]

Title: Multiple Polylogarithms in Weight 4 Speaker: Herbert Gangl Date: Tuesday, November 19, 2013 Time: 11:00am – 12:30pm Place: Seminar Room 313, Simons Center       [box, type=”download”]Watch the video.[/box] Abstract: It is well-known that all multiple polylogarithms of weight 2 and 3 are expressible in terms of Li_2 and Li_3, respectively, while the interplay […]

Title: Motivic Superstring Amplitudes Speaker: Stephan Stieberger Date: Thursday, November 14, 2013 Time: 11:00am – 12:30pm Place: Seminar Room 313, Simons Center       [box, type=”download”]Watch the video.[/box] Abstract: The structure of tree-level open and closed superstring amplitudes is analyzed. For the open superstring amplitude we find a striking and elegant form, which is bolstered […]
