Maths and physics outreach lectures in Isaac Newton Building


On Tuesday, 9th May 2017, the Lecture Theater of the Isaac Newton Building, was used for the first time for an outreach event, organised by Sandro Mattarei in collaboration with the university’s Marketing Team. Students from the Lincoln College attended a double lecture in Maths and Physics. Marco Pinna’s lecture on the mathematics of bird flocking was followed by a lecture on Platonic solids delivered by Sandro Mattarei.

Maths & Physics at Lincoln: EDT Headstart residential course


On 11th July 2017 several members of the School of Mathematics and Physics will contribute lectures and workshops to a Headstart residential course at the University of Lincoln (see EDT Headstart). Thirty students in Year 12 from all over the country will stay from 10th to 13th July to experience several taster session of Mathematics, Physics, and Engineering.

The Maths and Physics activities will span six hours of 11th July and include sessions on the following topics:

  • What is Chaos?
  • Patterns in nature: mathematical views of the natural world
  • Group Theory: algebra of transformations
  • Pascal’s triangle and the Sierpinski gasket
  • There’s more to light than meets the eye!

Algebraic conference in Lincoln

confSchool of Mathematics and Physics conducted the conference “Maximal Conditions and Embeddings of Profinite Groups” in University of Lincoln on 2nd June. The conference was supported by a grant of the London Mathematical Society under the ‘Celebrating New Appointments’ scheme, which was secured by Dr Anitha Thilaisundaram.  The participants included Prof Dugald Macpherson (Leeds), Prof Rögnvaldur G. Möller (University of Iceland, Reykjavik), Prof Peter Neumann (Oxford), Prof Dan Segal (Oxford), Prof John Wilson (Oxford), as well as young researchers from Australia, Germany, and UK. The talks were given by Alejandra Garrido (Düsseldorf), Simon Smith (Lincoln), Anitha Thillaisundaram (Lincoln), and John Wilson (Oxford); see the programme here.

After the conference a wine reception was addressed by the Pro Vice Chancellor of UoL / Head of College of Science and Engineering Prof Libby John and Prof John Wilson (Oxford). The reception was followed by the conference dinner.

Two talks at LARA seminar by Prof Rögnvaldur G. Möller and by Dr Colin Reid

Another enhanced Lincoln Algebra Research Afternoon (LARA) before the conference “Maximal Conditions and Embeddings of Profinite Groups” on 2nd June. On 31th of May we had two talks:

Prof Rögnvaldur G. Möller (University of Iceland), Minimal valency of a Cayley–Abels graph and group properties, 

Dr Colin Reid (ARC DECRA Fellow at University of Newcastle, Australia), Chief series of locally compact groups.

LARA seminar by Dr Alejandra Garrido

On 30th of May we had a P1030268aseminar within the Lincoln Algebra Research Afternoons (LARA), with Dr Alejandra Garrido (currently an Alexander von Humboldt research fellow at Duesseldorf) giving a talk on Congruence and profinite completions for groups acting on rooted treesP1030280aP1030261a

The next LARA seminar will be on 31st May 2017 with two talks, one by Röggi Möller (Univ. of Iceland), and another by Colin Reid (Newcastle Univ., Australia).

We enjoy several extra speakers at LARA seminars due to participants arriving in Lincoln for the forthcoming conference “Maximal Conditions and Embeddings of Profinite Groups” on 2nd June.

Sandro Mattarei gives a talk in Cambridge

On 24th May 2017 Sandro Mattarei visited the University of Cambridge and gave a seminar talk on Generalisations of self-reciprocal polynomials.

LARA seminar by Sandro Mattarei

On 16th of May reciprwe had a seminar within the Lincoln Algebra Research Afternoons (LARA), with Sandro Mattarei reporting on his recent work on Generalizations of self-reciprocal polynomials.

The next LARA seminar will be delivered on 30th May 2017 by Dr Alejandra Garrido (Duesseldorf), as part of her visit to Lincoln for the forthcoming conference “Maximal Conditions and Embeddings of Profinite Groups” .

AMS Special Session at Hunter College, City University of New York

The Special Session on Infinite Permutation Groups, Totally Disconnected Locally Compact Groups and Geometric Group Theory organised by Simon Smith (University of Lincoln) and Delaram Kahrobaei (City University of New York) took place this weekend, as part of the huge American Mathematical Society Spring Eastern Sectional Meeting held at Hunter College, City University of New York.

The idea behind the special session was to bring together three areas of infinite group theory that share a powerful tool: the analysis of group structure through an action on a locally finite graph. Subdegree-finite permutation groups act on an orbital graph, finitely generated groups act on a Cayley graph, and compactly generated totally disconnected locally compact groups act on a Cayley–Abels graph.

In the Special Session there were speakers from across the world: USA, Australia, Europe and South America. The talks were excellent. James Maynard (University of Oxford) gave the prestigious Erdös Memorial Lecture to the entire Sectional Meeting, where he spoke about his work on finding large gaps in the prime numbers.

Sandro Mattarei gives a talk at the University of Milano Bicocca

On 28th April 2017 Sandro Mattarei gave a talk at the University of Milano Bicocca, on Generalizations of self-reciprocal polynomials.  Sandro is approaching the end of a one-month stay at the University of Milano Bicocca as visiting professor, which has been a very exciting time. Besides completing a research project with Marina Avitabile, Sandro has had many opportunities for fruitful discussions with other members of the local Algebra group.
