This is the webpage of James D. Mitchell. I am a senior lecturer and a member of CIRCA, the Algebra, and the Analysis groups in the School of Mathematics and Statistics at the University of St Andrews. I am also a member of the Centre for Algebra at the University of Lisbon, Portugal, and of the Biomics project, which is part of the EU funded Unconventional Computation Cluster.

The computational semigroup theory blog contains some information about my recent activities.


17/04/2014 - A new version (2.0) of the Semigroups package for GAP is now available.

24/02/2014 - A new version (0.6.8) of the Smallsemi package for GAP is now available.

28/10/2013 - I updated the page containing data relating to semigroups and transformations here.

The website accompanying the paper ‘Groups that together with any transformation generate regular semigroups or idempotent generated semigroups’ by J. Araújo, J. D. Mitchell and Csaba Schneider is available here.
