# ICERM fall 2015

This wiki contains archived information related to the ICERM fall 2015 special semester Computational Aspects of the Langlands Program. This program included three topical workshops:

- Modular Forms and Curves of Low Genus: Computational Aspects (September 28-October 2, 2015)
- Explicit Methods for Modularity of K3 Surfaces and Other Higher Weight Motives (October 19-23, 2015)
- Computational Aspects of L-functions (November 9-13, 2015)

at whose individual web sites one may find more information, such as lecture notes.

## Weekly schedule template

Effective Sep 14-Dec 4, excluding workshop weeks (Sep 28-Oct 3, Oct 19-23, Nov 9-13) and holidays (Oct 12, Nov 26-27). For seminars at Brown, see below for directions.

The following activities are for graduate students/postdocs only, and so will not be listed in the weekly schedule: Peer to Peer Seminar; professional development roundtables; Jeff Hoffstein's graduate course.

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.

How to read this table: each row represents a 30-minute time block starting at the specified time. For instance, the research seminar starts at 4pm on Thursday.

## Getting to Brown

The Brown math department is located in Kassar House, at the corner of Thayer St. and George St. Options for getting there:

- Walk up the steep hill on Hopkins St., which becomes George. Allow 15 minutes.
- Take the bus from the stop at Waterman and North Main towards campus, get off at the first stop (tunnel and Thayer) and turn right (towards the tall tower that is the Science Library) on Thayer. The math department is 1.5 blocks that way. The bus costs $2.
- Brown runs a shuttle that stops across the street from ICERM and then goes to campus. You need to show a Brown ID to board. See schedule/tracker.
