# Conferences in arithmetic geometry

**Special notice** (updated 8 Mar 2020): Due to the global outbreak of novel coronavirus (COVID-19),
many events listed for spring/summer 2020 are likely to be postponed, cancelled, or held in an online-only format. Please confirm with conference organizers before making any travel plans. Listing a conference in MathMeetings with the country code "Antarctica" will make it show up as "online" in the following list.

This is a new incarnation of my list of conferences in arithmetic geometry, now powered by MathMeetings.net. Visit that site to see past listings or conferences in other areas of mathematics.

To add a new conference to this list, use the MathMeetings add page and include at least one of the subject tags "ag.algebraic-geometry" or "nt.number-theory".

To see the code for this front end (or the MathMeetings back end), see the MathMeetings git repository.

My wiki page still exists for the purposes of tracking "conference rumors" (uncorroborated by associated web sites).

In addition to MathMeetings itself, some other conference lists that may be of interest:

- Number Theory Web conferences page: more number theory, less algebraic geometry.
- Ravi Vakil's conference page: more algebraic geometry, less number theory.
- Topology Atlas: topology. Several other such lists (AlgTop-Conf, Sarah Whitehouse's conference page) have been merged into MathMeetings.
- Douglas West's conference page: combinatorics.
- commalg.org: commutative algebra.
- CStheory-Events: theoretical computer science.
- Sage wiki: Sage computer algebra development conferences (on various themes).
- IACR: cryptology.
- AMS Mathematics Calendar: general.
- SIAM calendar: SIAM conferences.
