Orbital graphs and constructive matrix recognition
Paula Hähndel (Martin-Luther-Universität Halle-Wittenberg) writes on her visit to St Andrews in Spring 2019, supported by CoDiMa: “My stay in St Andrews was a great opportunity to meet the local GAP community. I was encouraged to continue my improvements of parts of the GAP documentation, and I used some of my time during my stay […]
Algorithms for black box groups
CoDiMa partially supported the visit of Prof. Alexandre Borovik (University of Manchester) to Dr Sukru Yalcinkaya (Istanbul University) on 8-21 September 2018. They reported the following: In this short period of very intensive work in a small group (A. Borovik, S. Yalcinkaya (Istanbul University), and M. Lavrauw (Sabanci University)) we achieved a significant further progress […]
Computations in small overlap monoids
For several days in June 2018, Mark Kambites (Manchester) visited James Mitchell in St Andrews, supported by the CoDiMa research visits programme. The visit allowed Mark Kambites and James Mitchell to discuss algorithms for performing computations in small overlap monoids. Efficient algorithms for various problems in this important class of finitely presented monoids were developed by […]
Symmetry vs Regularity: The first 50 years since Weisfeiler-Leman stabilization
Madeleine Whybrow reports: With the support of CoDiMa, I attended the conference “Symmetry vs Regularity: The first 50 years since Weisfeiler-Leman stabilization” in Pilsen, Czech Republic. It was a very impressive event and nearly all of the major contributors to the field of algebraic graph theory over the past 50 years were present. There were some […]
Madeleine Whybrow’s second visit to St Andrews
I spent a week in St Andrews working with Markus Pfeiffer on an ongoing project which we are working on writing and implementing an algorithm to construct 2-closed Majorana representations. Funding for this trip was provided by CoDiMa. Majorana algebras are non-associate algebras used to study the Monster group and its subgroups. They can be studied […]
8th International Workshop on Parallel Symbolic Computation (PASCO’17)
The 8th International Workshop on Parallel Symbolic Computation (PASCO’17) took place in Kaiserslautern, Germany, July 23-24, 2017, and was co-located with the International Symposium on Symbolic and Algebraic Computation (ISSAC’17). This instance of PASCO continued the mission of promoting and advancing parallel algorithms and software in all areas of mathematical computation. It therefore occupies a unique space in the […]
Wedderga package coding sprint
In November 2017, Sugandha Maheshwary (IISER Mohali, India) and Ángel del Río (Murcia, Spain) visited St Andrews for a Wedderga package coding sprint. The main goal of the coding sprint was to incorporate new code developed by Sugandha Maheshwary and Gurmeet Bakshi, and prepare a new release of the package which will be compatible with the new […]
Leonard Soicher’s visit to Portugal
The CoDiMa project supported my participation in “All Kinds of Mathematics Remind me of You: Conference to celebrate the 70th Anniversary of Peter J. Cameron“, held at the University of Lisbon, 24-27 July 2017. This conference brought together many colleagues, students and collaborators of Peter Cameron, and a diverse range of interesting mathematical research (covering Peter’s diverse […]
Groups, Rings and the Yang-Baxter equation
In June 2017 Olexandr Konovalov took part in the conference “Groups, Rings and the Yang-Baxter equation” (Spa, Belgium). He gave a talk “GAP Group Rings Toolkit” with an overview of the functionality to work with group rings available in GAP and four of its packages, demonstrated the Jupyter kernel for GAP, and organised a coding sprint to work on […]
Visitor Madeleine Whybrow: Constructing Majorana Representations in GAP
After meeting at the Workshop on Permutation Groups: Methods and Applications in Bielefeld in Germany, Markus Pfeiffer became interested in some computational work which I am developing as part of my PhD. He kindly invited me to St Andrews to spend a week working together on my code. Funding for this trip was provided by […]
