CIRCA

The Centre for Interdisciplinary Research in Computational Algebra (CIRCA) was established in 2000 to foster new and existing collaborative research between members of the Schools of Computer Science and of Mathematics and Statistics in the area of computational abstract algebra.

The Centre undertakes mathematical research with computer assistance, develops new techniques for computation in abstract algebra and develops and distributes software implementing these techniques. This work is supported by research grants from the EPSRC, the Leverhulme Trust, the British Council, the European Commission and the Royal Society of Edinburgh.

The Centre also organises conferences, seminars and training courses and coordinates the international efforts to develop maintain and promote the GAP (groups, algorithms and programming) software package, a leading integrated system for computational discrete mathematics and algebra.

News and Events

All kinds of mathematics


A conference “All Kinds of Mathematics Remind me of You” to celebrate the 70th Anniversary of Peter Cameron took place in Lisbon on 24-27 July 2017. It was followed by a one-day workshop “Symmetry in Finite and Infinite Structures“. Both events took place at the University of Lisbon and were organised by mathematicians from Universidade Aberta and the Universities of Aveiro, Coimbra and Lisbon, led by João Araújo.

Quoting the School newsletter, participants ranged in academic age from Peter’s own DPhil supervisor Peter Neumann to recent St Andrews undergraduate Scott Harper. They included more than twenty co-authors including three with nine or more joint publications with him. The other participants from St Andrews were Rosemary Bailey (who spoke on “Circular designs with weak neighbour balance”), Collin Bleak, Julius Jonusas (“Universal words and sequences”), James Mitchell (“Semigroups from digraphs”), Shayo Olukoya (“Growth rates of automata groups generated by reset automaton”) and Wilf Wilson (“Maximal subsemigroups of monoids of partial order-(anti)endomorphisms”).

The final talk has been given by Peter himself and was entitled “Perchance to dream …”. It mentioned several outstanding problems, and Peter hopes that participants will solve many of these before the next conference!

In a series of five blog posts, Peter gave a detailed account of each day: see those for day 1, day 2, day 3, day 4 and the workshop.


Peter Cameron awarded the 2017 LMS Senior Whitehead Prize


Congratulations to Peter Cameron on being awarded the 2017 Senior Whitehead Prize of the London Mathematical Society! The prize is awarded for ‘exceptional research contributions across combinatorics and group theory, his fertile imagination and encouragement of others having sparked activity in many fields’. He became the third person to win both a Junior and Senior Whitehead Prize. Please read further details in the LMS announcement and in this post in Peter Cameron’s blog.
