A workshop on computational methods in group theory and algebraic geometry, in the context of the Computer Algebra system Magma. The meeting was particularly concerned with exploring interactions between computational group theory and computational algebraic geometry. This was the fourth in a series of Magma conferences: the previous one was held at Institute Henri Poincaré, Paris, October 4 - 8, 2004.

    The meeting was built around the following types of activities:

  • Lectures describing recent advances in algorithmic methods
  • Talks describing significant applications of Magma to one of the thematic areas.
  • Talks discussing future directions for computational methods in the thematic areas.
  • Tutorials on the use of Magma in the following areas:
    1. Finite permutation and matrix groups
    2. Representation theory
    3. Schemes
    4. Algebraic curves
