Workshop on Geometric and Topological Combinatorics
- A satellite conference of ICM 2006 -

Alcalá de Henares (Madrid, SPAIN)
August 31-September 5, 2006
With support from


Geometric and/or topological combinatorics concerns discrete structures that arise in a wide array of mathematical contexts, ranging from enumerative questions about polytopes and other constructions from linear algebra to the topology of manifolds and algebraic varieties. This workshop is intended as an informal discussion forum for people from such fields as combinatorics, discrete geometry, algebraic geometry, convex geometry, algebraic topology, combinatorial optimization and theoretical computer science, among others.

This activity is coordinated with the advanced course Combinatorial and Computational Geometry: Trends and topics for the future, organized by the Centre de Recerca Matemàtica (CRM). Both will take place in the same days and place, with sessions of one and the other intertwined. Registration and accomodation for both events are maintained by the CRM.
