Seminar in Lincoln

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.

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” .

Visit by Professor Andrei Jaikin-Zapirain

Algebra Seminar in Lincoln: talk by Andrei Jaikin-Zapirain

Professor Andrei Jaikin-Zapirain (Universidad Autonoma de Madrid) will speak in the Algebra seminar on Wednesday,  10 May 2017, at 2:00pm in room JBL0C05 (Joseph Banks Laboratories, which is building 22 on the university’s map). The title of his talk is On l2-Betti numbers and their analogues in positive characteristic, and here is an Abstract.

Visit by Dr Rachael Camina

P1020968aDr Rachel Camina (University of Cambridge)  visited School of Mathematics and Physics on  29 March 2017. She gave a talk “Vanishing Class Sizes” at the Algebra research seminar. P1020977a

Algebra Seminar in Lincoln: talk by Rachel Camina

Dr Rachel Camina (University of Cambridge) will speak in the Algebra seminar on Wednesday,  29 March 2017, at 1:30pm in room MB1019 (Minerva Building, which is building 1 on the university’s map). She will talk about Vanishing Class Sizes.

Abstract: For many years authors have considered the algebraic implications of arithmetic conditions on conjugacy class sizes for finite groups. We look at recent results and consider the restricted case when just vanishing class sizes are considered.

LARA seminar by Evgeny Khukhro

On 14th March 2017 we enjoyed another seminar within the Lincoln Algebra Research Afternoons (LARA), with Evgeny Khukhro reporting on his recent study of Almost Engel finite, profinite, and compact groups.

The next LARA seminar will be delivered by Sandro Mattarei on 16th May 2017.

Lincoln Algebra Research Afternoons

We have recently started to run an informal seminar within our Lincoln Algebra group, where we tell each other about some topic that we are working on, or interested in working on, with the aim of promoting possible collaborations between us. This is run in a more informal way than the ordinary Algebra Seminar with outside speakers. We highly encourage interruptions for questions and discussions at any time.

Our PhD student Valentina Iusa started the series on 17th January 2017, by reporting on a problem she studied in 2015 as a final project for her Italian Laurea Magistrale (which is roughly equivalent to a master’s degree). She described a new take on Hans Zassenhaus’ classification of finite near-fields.

Anitha Thillaisundaram (in the photo) followed on 14th February 2017. She gave us an introduction to branch groups and some interesting problems in the area.

The next seminar will be given by Evgeny Khukhro on 14th March 2017. He will tell us about almost Engel groups.
