Through the past century, Lie theory has developed in several directions, finding important applications in other areas of mathematics and physics.
There exist deep connections among these directions. First of all, techniques and tools are often very similar. Secondly some problems that arise in one context naturally induce questions that find their solution in another one. The combinatorics of root systems and Coxeter groups, for instance, is one of the fundamental ingredients in Lie theory, and some problems not directly connected with this language eventually amount to combinatorial statements.
This is the case, for instance, of the problem of classifying finite and infinitedimensional Lie algebras, studying symmetric and spherical varieties, as well as topological properties of hyperplane arrangements. In the same vein, some of the most significant results in the combinatorics of Coxeter groups are handled via the geometry of the above varieties, or the representation theory of Lie algebras.
We believe that the collaboration between Lie theorists that have distinct education and interests may constitute a fundamental ingredient for our goals.
In this special period we would like to focus mainly on the following themes:
The idea of the Intensive Period is to have some interesting mini courses for PhD students and researchers and regular talks, but also time for discussions and collaboration in the beautiful setting of the city of Pisa.
A workshop will take place during the third week of February.
Please also see Planned activities for more detailed information about the programme.
Some funds will be available to offer financial support to a limited number of selected young researchers and students. See the section Financial Support for more details and for applications. Priority will be given to applications submitted by September 7th, 2014.
