Magma Workshop on Group Theory and Algebraic Geometry

## 22-26 August 2005

A workshop on the Computer Algebra system
Magma and its use in group
theory and algebraic geometry was held on 22 - 26 August 2005 at the
Mathematics Institute,
University of Warwick,
Coventry, UK.
This meeting was organized by

### Description

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.
### Themes

Group theory
Representation theory
Lie theory
Algebraic geometry
Arithmetic geometry

### Activities

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:
- Finite permutation and matrix groups
- Representation theory
- Schemes
- Algebraic curves

### Conference funding

Some LMS funding was available to provide expenses for speakers,
and limited travel and subsistence support for
graduate students based within the UK.
