Lie Group/Quantum Mathematics Seminar
Organizers Lisa Carbone, Yi-Zhi
Huang, Jim
Lepowsky and Siddhartha Sahi.
Time Friday, 12:10 pm to 1:10 pm (Eastern time).
Place Hill 705 or online via Zoom (see below for the Zoom link and passcode).
YouTube channel Rutgers Lie Groups Quantum Math Seminar.
Starting from Spring, 2008, the
Lie Group Seminar and Quantum Mathematics Seminar
have merged together to a single seminar called the
Lie Group/Quantum Mathematics
Seminar. The information on seminar talks can also be found in the Seminars & Colloquia Calendar page in the department.
For the Lie Group/Quantum Mathematics seminar in previous
semesters, see this
page.
For talks in the Quantum Mathematics Seminar from Spring, 1998 to
Fall, 2007, see
this page.
For a few years before 2008, the Quantum Mathematics Seminar
shared the time and place with the Algebra Seminar.
For talks in both the Algebra and
Quantum Mathematics Seminars in these few semesters, see the page
for
the Previous Rutgers Algebra Seminars. For all the seminars and colloquia in the department, see
the Seminars & Colloquia Calendar page.
Spring, 2025
In this semester, the seminar will be mostly in person. Occasionally there might be online talks using zoom.
See the information below on each talk.
For online talks, here is the information for the zoom meeting:
Zoom link: https://rutgers.zoom.us/j/93921465287
Meeting ID: 939 2146 5287
Passcode: 196884, the dimension of the weight 2 homogeneous subspace of the moonshine module
Some of the talks will be recorded and will be placed in the YouTube Channel for the seminar.
Upcoming talks
- Speaker Matteo Parisi, Harvard CMSA
- Title Amplituhedra & Scattering Amplitudes: A Novel Combinatorial-Geometric Approach to Particle Physics
- Time/place 5/9/2025, Friday, 11:00 am (Eastern Time), Hill 705 (in person)
- Abstract Recent studies of scattering amplitudes—the probabilities of particle interactions in quantum field theory—have led to remarkable connections with algebraic combinatorics and geometry. A striking example is the amplituhedron, a novel object whose volume gives scattering amplitudes in planar N=4 super Yang-Mills theory. Computing this volume requires decomposing (or tiling) the amplituhedron into smaller pieces (or tiles) and summing their volumes. In this talk, I will introduce the amplituhedron, explain its ties to the Grassmannian and total positivity, and discuss our recent advances in understanding its tiles, tilings, and novel connections with cluster algebras.
