Working Seminar on Algebraic Number Theory

Class groups and Galois cohomology
Shilin Lai
2:15pm|Princeton University, Fine 1201

From Romyar's AWS notes:

  • Section 5.1, especially: Prop 5.1.5, Cor 5.1.9, Rem 5.1.10, Ex 5.1.11

From McCallum-Sharifi:

  • Explain why $\mathbb{Q}(37^{1/37})$ has class number prime-to-37 (this is Cor 7.6). It may simplify the proof to use Cor 5...

Hida theory and Ohta's canonical comparison map
Giada Grossi
2:15pm|Princeton University, Fine 1201

From Romyar's AWS notes:

  • Sections 4.1 and 4.2.

Regarding the proof of Ohta's comparison isomorphism:

Working Seminar on Algebraic Number Theory

p-adic L-functions in one and two variables
Kim Tuan Do
2:15pm|Simonyi Hall 101

Introduce the L-function, and then the p-adic L-function, of a cusp form, and the of a Hida family of cups forms. What we need is in Fukaya-Kato Sections 4.4-4.5. See also: Mazur-Tate-Teitelbaum and Mazur's "Anomalous eigenforms" note.

Working Seminar on Representation Theory

Categorification of the positive half of $\mathbb{U}_q(\mathfrak{sl}_2)$
11:00am|S-101

We will talk about the categorification of the positive half of the quantum group $\mathbb{U}_q(\mathfrak{sl}_2)$ using the module categories over NilHecke algebras. We hope to explain the idea of categorification using this example.

Working Seminar on Representation Theory

$\mathbb C$-representation theory of $p$-adic groups through the glass of types
11:00am|S-101

It is well known that representations of open compact subgroups (called types) play a fundamental role in studying representations of $p$-adic groups. We give an overview of the theory (after Bernstein, Moy-Prasad, Bushnell-Kutzko) in connection...
