Charlotte Scott Centre for Algebra

The University of Lincoln has hosted a EDT Headstart  residential, where thirty students in Year 12 from all over the country have stayed from 1st to 3rd July 2019 to get an introduction to university life at Lincoln, to visit the facilities of our campus, but especially to experience several lectures and workshops in Mathematics and Physics. Two afternoon sessions devoted to academic tasters were held by the School of Mathematics and Physics, and coordinated by Dr Sandro Mattarei. On 1st and 2nd July the students enjoyed the following sessions:

  • Binomial coefficients modulo a prime – A lecture given by Dr Sandro Mattarei
  • Group Theory: algebra of transformations – A lecture given by Dr Simon Smith
  • What is the ‘Butterfly Effect’? – A lecture given by Dr Matthew Booth
  • Cassini: Over a decade of discoveries – A lecture given by Dr Phil Sutton

Before the last lecture the students sat…

Charlotte Scott Centre for Algebra

On Wednesday the 26th of June 2019, Gunnar Traustason (University of Bath) will give a seminar at the Charlotte Scott Centre for Algebra. He will be with us from the day before, when he will act as external examiner in the PhD viva of Valentina Iusa.

Gunnar’s talk will be at 9:30am in INB3305.

Title: Powerfully nilpotent groups.

Abstract: In this talk we will introduce a special subclass of powerful p-groups that we call powerfully nilpotent groups and are p-groups that possess a central series of a special kind. We will describe some structure theory and discuss ‘classification’ in terms of an ancestry tree and powerful coclass.

On the 20th of June 2019 Dr Rachel Skipper (Georg-August-Universität Göttingen and École Normale Supérieure de Lyon) visited Charlotte Scott Centre for Algebra and gave a talk  “On the Cantor–Bendixson rank of the Grigorchuk group and the Gupta–Sidki 3-group”. Her visit is supported by the London Mathematical Society Grant Scheme 2 (Visits to the UK) and by the Lincoln Institute of Advanced Studies.

Abstract: We study the Cantor–Bendixson rank for the space of subgroups of the Grigorchuk group and the Gupta–Sidki group. In particular, we show that for $latex G$ the Grigorchuk group or the Gupta–Sidki 3-group, the Cantor–Bendixson rank of $latex Sub(G)$ is $latex omega$. This is a joint project with Phillip Wesolek.”

In May 2019, Anitha Thillaisundaram visited the University of the Basque Country in Bilbao to collaborate with Gustavo Fernandez-Alcober, Şükran Gül and Elena Di Domenico on projects involving groups acting on rooted trees. This visit was partially supported by a Lincoln Institute of Advanced Studies Mobility Grant. Anitha also participated in a course at the Autonomous University of Madrid on “Growth and relations of graded rings”, which also included Golod–Shafarevich groups.

On 10 June 2019 The University of Lincoln opened an exhibition of research images by staff and research students. As a part of the opening ceremony the winners were announced of Images of Research Competition 2019. Amongst the staff research images the panel awarded the prize to “Chaotic beats” by Dr Fabien Paillusson and our undergraduate physics student Michael Milburn, which research was conducted with the help of Dr Matt Booth. Read an extensive blog post on chaos by Fabien here.
