Overview

The aim of this focused research workshop is to bring together mathematicians working in two different, but related, fields: Exterior Differential Systems and Cartan’s Equivalence Method on the one hand and Lie theory (especially Lie pseudo-groups and Lie groupoids/algebroids) on the other. Not only there have been some very exciting advances in these subjects recently, but also it has became clear in the last few years that these areas are intimately connected. Hence, given the current interest by different groups of people and different viewpoints, there is a need for a focused workshop which can bring together the top researchers, promising young researchers, and students in these very active fields

Activities include two mini-courses presented by Robert Bryant (MSRI) and Marius Crainic (Utrecht), discussion sessions, and research talks.
