Is algebra a spoilsport in mathematics? a public lecture by Professor Evgeny Khukhro University of Lincoln Wednesday, 17 January 2018, 6:00-7:20 pm Newton Lecture Theatre INB0114 in the Isaac Newton building, University of Lincoln Book a place Is it the role of algebra to be taking fun out…]]>

Distinguished Maths & Physics Public Lectures

Is it the role of algebra to be taking fun out of mathematics? Starting from primary school level, there are numerous examples in which lively mathematical problems are “dried up” by algebra. Or could one experience a different, sublime kind of satisfaction from application of algebraic methods? I will discuss these questions both from the historical perspective and on the basis of personal experience.

Evgeny Khukhro is a Professor of Pure Mathematics in School of Mathematics and Physics of University of Lincoln. Evgeny received his PhD in 1980 in algebra from Novosibirsk University, Russia, and DSc (Habilitation) in 1988 in group theory from Sobolev Institute of Mathematics of Siberian Branch of Russian Academy of Sciences…

On 5th December I visited Lincoln Astronomical Society and their observatory. I gave a talk titled “Fantastic worlds and where to find them”, where we discussed how some of the most recently discovered exoplanets were detected. We then looked at what some of these worlds might be like and where is best to look for life in our own solar system. This was finished with some interesting questions about future work and potential life on other worlds.

The LARA seminar on the 5th of December was given by Callum Burrows. The title of his talk was “Properties of group actions and their relation to wreath products”.

*Abstract:* We explore some of the basic properties of group actions, namely *k*-transitivity, *k*-homogeneity and *k*-primitivity along with examples of such corresponding groups. We will establish how to demonstrate these properties using various methods including the use of orbital graphs in conjunction with useful results such as Higman’s criterion. Wreath products prove to be very useful in the context of permutation groups, as they serve as a universal example of embedding groups for imprimitive groups.

Elena Patyukova and Paul Topham from Aston University and Martin Greenall from the University of Lincoln have recently secured laboratory time at the ESRF X-ray facility in Grenoble. The experiment, which will take place in March 2018, will test the predictions of their own mathematical model on the role of hydrogen bonding in polymers. The theoretical side of their project uses results from graph theory and integer sequences, and has benefitted from discussions with members of the Algebra group in Lincoln.

Dr Stefano Leoni is a Reader in Computational Chemistry, School of Chemistry, Cardiff University. His research focuses on structural and electronic phase transitions, chemical reactions, formation mechanisms, reactive intermediates, structure prediction and the rules behind polymorphism in general. Dr Leoni investigations aim at understanding processes like crystallization, nucleation and growth, diffusion of impurities or defects, or electrochemical reactions, all crucial factors for the development of better materials.
