Number Theory Seminar @ University of Melbourne

Alex Ghitza and I are running a working seminar on things number-theoretic.

Time: 13:00--14:00 Tue. (Melbourne local time) for 2024S2.

The theme for 2024S2 is an arithmetic introduction to Shimura varieties. We will mostly follow "Jared Weinstein. Reciprocity laws and Galois representations: recent breakthroughs. Bull. Amer. Math. Soc. (N.S.), 53(1):1–39, 2016."

Time: 13:00--14:00 Mon. (Melbourne local time) for 2024S1.

Venue: Peter Hall 162 (The 🌟NEW🌟 seminar room)

Please go to the Number Theory Research Group website where you can find a link to join our mailing list. You will receive the Zoom link and announcements of talks.

Groups over local fields: Step one towards Ξ“\G/K
I want to try to make a basic path to these coset spaces, using the kinds of tools we use in first year Linear algebra and 2nd year GTLA. The key idea is to consider infinite n-periodic matrices in place of the n x n matrices that are used in first and second year. The hope is that, once one sets up infinite n-periodic matrices cleanly, then all that remains is to redo what is done in first and second year in this setting.

Introduction to the "Reciprocity laws" survey by Jared Weinstein

23 July 2024

Modular Forms and Galois Representations
I will begin by recalling the basic facts about Tate modules of elliptic curves. Building on this discussion, I will recall the basic facts about Galois representations attached to modular forms, and sketch the proofs of some of them.
This is the preliminary talk to the talk, From Modular Curves to Categorification, in the representation theory seminar on 25 July, also given by Matt. More details are on the representation theory seminar webpage.

Last talk of 2024S1. We will resume in 2024S2.

There may be special talks during the Winter break, in which case, we will send out announcements.

Parabolic Induction and Eisenstein Series with examples
Chengjing Zhang
This talk focuses on parabolic induction and Eisenstein series. We will discuss how induction, a powerful tool in the representation theory of finite groups, appears as parabolic induction in the theory of automorphic representations. Although parabolically induced representations are not automorphic themselves, they can be associated with automorphic representations through Eisenstein series.
