II Latin American School of Algebraic Geometry and Applications (II ELGA)

Hotel
La Plage , Cabo Frio, RJ, June, 1 – 12

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 4 mini-courses covering different aspects of Algebraic Geometry, all taught in English. There will be also 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.
