Probability Seminar: The planar Coulomb gas on a Jordan curve
April 2, 2024 1:30 pmSpeaker: Klara Courteaut
The eigenvalues of a uniformly distributed unitary matrix have the physical interpretation of a system of particles subject to a logarithmic pair interaction, restricted to lie on the unit circle...

**CANCELED** CMSA Colloquium: Errors and Correction in Cumulative Knowledge **CANCELED**
April 1, 2024 4:30 pmSpeaker: Madhu Sudan
**CANCELED** Societal accumulation of knowledge is a complex, and arguably error-prone, process. The correctness of new units of knowledge depends not only on the correctness of the new reasoning, but...

Thursday Seminar: The THH of the cochains of the circle
March 28, 2024 3:30 pmSpeaker: Ishan Levy
We will study the THH of the fixed points of a ring spectrum by a trivial Z-action as a cyclotomic spectrum. In particular, we will see that the coassembly map...

Richard P. Stanley Seminar in Combinatorics: Positivity in real Schubert calculus
March 27, 2024 4:15 pmSpeaker: Steven Karp
Schubert calculus involves studying intersection problems among linear subspaces of C^n. A classical example of a Schubert problem is to find all 2-dimensional subspaces of C^4 which intersect 4 given...

Number Theory Seminar: “everywhere unramified” objects in number theory and the cohomology of GLn(Z)
March 27, 2024 3:00 pmSpeaker: Frank Calegari
One theme in number theory is to study objects via their ramification: the discriminant of a number field, the conductor of an elliptic curve, the level of a modular form,...

Mathematical Picture Language Seminar: Certifying Almost All Quantum States with Few Single-qubit Measurements
March 26, 2024 4:30 pmSpeaker: Robert Huang
Quantum systems can exhibit highly complex entanglement. Certifying that an n-qubit state in the experimental lab is close to a highly-entangled target state typically requires deep entangling circuits or exponentially...
