ICERM fall 2015
This wiki contains information related to the ICERM fall 2015 special semester Computational Aspects of the Langlands Program, including the latest announcements from the organizers and schedule information for non-workshop weeks. For workshop weeks, please consult ICERM's official web pages: Sep 28-Oct 3, Oct 19-23, Nov 9-13.
For security reasons, one must log in to edit content; please contact one of the organizers for the communal login/password. Each week's schedule will be finalized and transmitted to ICERM the previous Thursday evening; if you make any changes after that time, please also notify Jeff Hoffstein so that ICERM can copy the changes over. (For help with wiki tables, read this.)

Announcements
- The 10th floor classroom is available as a collaborative space. The ICERM conference room is available as a quiet working space, especially for graduate students. To book one of these rooms for an activity, see Danielle Izzi at the front desk.
- ICERM has posted a list of visitors with arrival and departure dates.
- The questions mentioned during the discussion on the first day of the program in pdf form
- The organizing meeting for the algebra/NT and algebraic geometry seminars at Brown will take place on Wednesday, September 16. Dan Abramovic writes:
The Brown algebra and algebraic geometry seminar organizing meeting will take place on Wednesday, September 16, at 4pm in Kassar room 205.
Please note special day, time and location.
Please come and provide your suggestions, or send your suggestions in case you can't make it. Also let us know if you would like to be taken off this list, or if you know of someone who would like to join it. The algebra seminar will continue to convene Mondays at 4 in Kassar 105. It is organized by Steve Lichtenbaum and Mike Rosen. The algebraic geometry seminar on Fridays at 3 in Kassar 205. It will be organized by some subset of Nathan, Brendan, Melody and me.
The first scheduled seminar is on Friday, September 18 at 3pm, when Irene Bouw (Ulm) will speak.
Title: Existence of covers of curve in positive characteristic
Abstract: We discuss some results on the existence and nonexistence of covers of curves with prescribed tame ramification in positive characteristic, We consider construction of covers in positive characteristic using stable reduction of covers in characteristic zero. This yields results on Hurwitz curves.
- Jeff Hoffstein will be teaching a graduate course this semester that may be of interest to some junior participants. To quote:
Hi Everyone,
I'll be giving what is essentially a second year graduate class in analytic algebraic number theory. It will start this coming Tuesday and will be held, at the moment, from 2:30 - 3:50 on Tuesdays and Thursdays in Kassar 105 in the math dept on the corner of George and Thayer. The class will develop the basic theory of algebraic number fields, and present Hecke's approach to obtaining the analytic continuation and functional equation of the Dedekind zeta function. Please let me know if you might be interested in attending. If there is sufficient interest I will move the class to ICERM.
--Jeff Hoffstein
- There will be an AGNES (Algebraic Geometry Northeastern Series) conference October 2-4, immediately after the first thematic workshop; this includes a public lecture Friday evening by Jordan Ellenberg. Those wishing to attend are asked to register here as soon as possible.
- ICERM is soliciting proposals for their new Collaborate@ICERM program, in which groups of 3-6 gather for focused research. Applications from collaborations originating from semester programs are specially encouraged!
This week schedule
Unless otherwise specified, activities will take place in the 11th floor lecture room.
