Foundations of Computational Mathematics

Santander, June 30 - July 9, 2005

Workshop on Computational Algebraic Geometry
June 30 - July 2, 2005










The workshop will focus on Effective and Algorithmic Methods in  Algebraic Geometry, Commutative Algebra, Computational Algebra, and related fields.  The topics include, but are not restricted to,  Symbolic, Numerical and Symbolic-Numerical techniques, and Theoretical and Practical Complexity Issues.

The aim is to encourage interaction between the different approaches, and the emphasis will be on communicating ideas to a broadly based audience.

The FoCM plenary speakers associated to this workshop are

Schedule of the talks:

The talks are of 40', 30' or 20', plus after each talk  5' for questions and comments (that's why the slots are 5' longer),  and 5' for stretching legs between talks.
