Graduate Student Seminar

Organiser: Henri Darmon.
Time: Thursdays when there is no number theory seminar, in Room 1120 from 10:30-12:00.
Thursdays when there is a seminar, right after the afternoon talk, in the CICMA room (from around 4:30-5:30).

This seminar is aimed primarily at the graduate students, postdocs and faculty in the arithmetic geometry group. It will be comprised mainly of talks by graduate students presenting the questions they are thinking about in order to share their progress, as well as their doubts and confusions, with others in the group. Talks will typically run for 50 minutes. Suggestions by students, post-docs and faculty of talks that are both self-contained and of broad appeal are invited and strongly encouraged.

Here is the schedule so far:

September 7. Organisational meeting.

Roughly four 30 minute talks by whatever willing victims we can muster, on the general theme of "what I did over the summer". Volunteers are encouraged to step up.

10:00-10:30. Shousen Lu. Bianchi modular forms and modular symbols.

10:30-11:00. Marti Roset Julia. Some calculations with half integral weight forms.
September 21.
10:30-11:30. Ting Han Huang. Special values of triple product p-adic L-functions for finite slope families.

I also propose that we watch (on our own) the lecture of Nicolas Bergeron which is posted on line, and discuss it together over lunch (in the 10th floor lounge), after the seminar of Ting Han).
October 5. This week we might have an irregular schedule, because of the Langlands for spherical varieties mini-course. Also, I will unexpectedly be out of town that day.
Muhammad Manji will be visiting from Warwick via Toronto and we hope he will give a talk, schedules permitting.
October 19.
John Jae Hyung Sim (Boston University) Explicit Dedekind-Rademacher cocycles.

For our lunch discussion, I propose that we discuss the following lecture by Loic Merel whose link was kindly forwarded to me by Robin Zhang.
November 2.
Shousen Lu. Special values of Dedekind zeta functions, volumes of hyperbolic manifolds, and Eisenstein series.

I would like to devote our lunchtime discussion to the Nekovar-Scholl plectic conjectures, based on the lectures by Tony Scholl and by Michele Fornea at the Nekovar memorial conference.
November 16. From 11 AM to 11:50 I will be speaking in the Number Theory Web Seminar. This talk could double as the "presentation of the week" and we could meet afterwards and discuss it over lunch. Note that, to participate in the NT Web seminar, you do need to register. It take a few minutes but you shouldn't forget!
November 30.
December 14. No seminar held that day.
January 24. Hazem presented on Higher Greens functions.
February 1. Hazem on Higher Greens functions, cont'd.
February 8. Hughes on archimedean intersection theory, building on Hazem's presentations.
February 15. Pierre Charollois will be in town and will give an hour-long presentation on the Bergeron-Charollois-Garcia cubic cocycles. This will be the theme of our lunchtime discussion the week after.
February 22. Talk TBA. Lunchtime discussion on BCG cocycles.
March 14. (Pi day!) Hazem will speak, at Concordia after the afternoon lecture.
March 21. Marti will speak, at McGill in the morning, about cocycles for SL_n(Z).
March 28. Jonathan Love will speak at Concordia in the afternoon after the QVNTS.
April 4.
April 11.
April 18. No seminar, as I will be in Schiermonnikoog.
April 25. Shousen will speak on the work of Trifkovic and how it relates (or doesn't) to the rigid meromorphic Bianchi cocycles that Arihant has discussed.
May 2. Robin Zhang will be in town and will present his perspectives on the Stark and Harris-Venkatesh conjectures.
May 9. Elias Cairo will speak about the Heegner-Stark approach to Gauss's class number one problem and its analogue using Stark-Heegner points.
May 16. We will not have a meeting on this day.
