Summer blockbuster: Manhole Cover!


Making last-minute preparations for my visit to Brazil, to give a short course on algebraic cycles and birational geometry, I decided to visit the US State Department website for any travel advisories. Almost everything there was as expected. Almost.

Visitors should also remain alert to the possibility of manhole cover explosions. There have been multiple manhole cover explosions in Rio de Janeiro in the past few years, with a higher incidence in the Centro and Copacabana neighborhoods.

On further investigation, I see that these menaces do their best to lure you in:

ELGA @ IMPA, 1–12 June 2015

rio-catThe Second Latin American School of Algebraic Geometry and Applications (II ELGA) will take place from June 1st to 12th, 2015, at Hotel La Plage, Cabo Frio, State of Rio de Janeiro.

The goal of this CIMPA research school is to train young mathematicians working in Latin America in some of the most active areas of research in algebraic geometry, as well as to promote greater interaction among researchers and students, and to build a network of collaborations. The first week of the school will consist of four mini-courses covering different aspects of algebraic geometry, all taught in English. (I will be giving a course about the integral Hodge conjecture.) There will also be poster presentations by young researchers and students. The second week will consist of research talks by leading specialists, as well as presentations by young researchers.

Registration is open, with a deadline of January 18th, 2015, for participants from outside Brazil.

Algebraic Geometry 2015

craig-armstrong-climbing-adopted-cat-millie-6-600x799Algebraic geometry is fortunate to have the established tradition of a major discipline-spanning meeting every decade. The next such meeting will be held in Utah from July 12th to August 1st, 2015, with a preceding graduate student bootcamp from July 6th to 10th.

Registration is now open, with a deadline of January 15th, 2015.

I am organizing a seminar in the third week, with the following speakers:
Aravind Asok, Joseph Ayoub, Nicolas Bergeron, Patrick Brosnan, Aise Johan de Jong, Moritz Kerz, Bruno Klingler, Max Lieblich, Alena Pirutka, Shuji Saito, Christian Schnell, Zhiyu Tian

IAS Workshop 9-13 March 2015: Chow Groups, Motives, and Derived Categories

wain-catsRegistration is now open. The Institute does not offer funding for visitors to this workshop; however, registration is free.

This workshop is part of the topical program “The Topology of Algebraic Varieties” taking place during the 2014-15 academic year at the Institute for Advanced Study. One theme of the workshop is the Chow group of algebraic cycles on an algebraic variety, and the related concept of motives. A recent advance is the application of Chow groups to birational geometry, for example showing that very general quartic 3-folds are not stably rational. The workshop also covers derived categories of algebraic varieties, which also have exciting interactions with birational geometry.

IAS Workshop 13-17 October 2014: Fundamental Groups and Periods

This workshop is part of the topical program “The Topology of Algebraic Varieties” which will take place during the 2014–2015 academic year at the Institute for Advanced Study. One theme of the workshop is to present the latest work on the possible fundamental groups of algebraic varieties. The other theme is periods of integrals, such as multiple zeta values, which are related to fundamental groups via Hodge theory, and also mixed Tate motives.

Registration for this workshop is now open at the IAS site:

There is also an unofficial website that aims to give information about activities surrounding the Institute special year:
