Speaker: Pavel Etingof (MIT)In person or on Zoom: https://mit.zoom.us/j/92441268505Title: Periodic pencils of flat connections and their p-curvatureAbstract: A periodic pencil of flat connections on a smooth algebraic variety $X$ is a linear family of flat connections $ abla(s_1,...,s_n)=d-\sum_{i=1}^r\sum_{j=1}^ns_jB_{ij}dx_i$, where $\lbrace x_ibrace$ are local coordinates on $X$ and $B_{ij}: X\to {m Mat}_N$ are matrix-valued regular functions. A pencil is periodic if it is generically invariant under the shifts $s_j\mapsto s_j+1$ up to isomorphism. I will explain that periodic pencils have many remarkable properties, and there are many interesting examples of them, e.g. Knizhnik-Zamolodchikov, Dunkl, Casimir connections and equivariant quantum connections for conical symplectic resolutions with finitely many torus fixed points. I will also explain that in characteristic $p$, the $p$-curvature operators $\lbrace C_i,1\le i\le rbrace$ of a periodic pencil $ abla$ are isospectral to the commuting endomorphisms $C_i^*:=\sum_{j=1}^n (s_j-s_j^p)B_{ij}^{(1)}$, where $B_{ij}^{(1)}$ is the Frobenius twist of $B_{ij}$. This allows us to compute the eigenvalues of the $p$-curvature for the above examples, and also to show that a periodic pencil of connections always has regular singularites. This is joint work with Alexander Varchenko.

Seminar

IAP is a unique opportunity to join the Latinx Graduate Student Association Dance classes and stay warm during winter! Led by the experienced instructor Liliana Jimenez, we'll be hosting a short series of five sessions dedicated to Bachata. We warmly invite you to join us! Where: Kresge Auditorium (W16-033)When: First class 4:30 - 5:30 pm on Friday Jan 10thRemaining classes: 5:00 - 6:00 pm on Fridays Jan 17th, 24th, 31st and Feb 7th Attendace is limited to 25 students per lesson (make sure to click "I'm interested"!). The classes are designed for beginners and will progress gradually, so we encourage you to attend all sessions if possible. However, feel free to join the classes that align with your schedule. Thanks to the IAP mini-grant for funding this event.
