Euler’s pioneering equation: ‘the most beautiful theorem in mathematics’ - Robin Wilson

Euler’s equation, the ‘most beautiful equation in mathematics’, startlingly connects the five most important constants in the subject: 1, 0, π, e and i. Central to both mathematics and physics, it has also featured in a criminal court case and on a postage stamp, and has appeared twice in The Simpsons. So what is this equation – and why is it pioneering?

Robin Wilson is an Emeritus Professor of Pure Mathematics at the Open University, Emeritus Professor of Geometry at Gresham College, London, and a former Fellow of Keble College, Oxford.

Can Mathematics Understand the Brain? - Alain Goriely

The human brain is the object of the ultimate intellectual egocentrism. It is also a source of endless scientific problems and an organ of such complexity that it is not clear that a mathematical approach is even possible, despite many attempts. 

In this talk Alain will use the brain to showcase how applied mathematics thrives on such challenges. Through mathematical modelling, we will see how we can gain insight into how the brain acquires its convoluted shape and what happens during trauma. We will also consider the dramatic but fascinating progression of neuro-degenerative diseases, and, eventually, hope to learn a bit about who we are before it is too late. 

Alain Goriely is Professor of Mathematical Modelling, University of Oxford and author of 'Applied Mathematics: A Very Short Introduction.'

Elsevier supports mathematics at Oxford with £1 million donation

Global information analytics business Elsevier is donating £1 million to Oxford Mathematics, in support of fellowships, research meetings and workshops.

Oxford Mathematics is widely recognised as one of the foremost centres for the subject globally; its strength and reputation has never been greater. Now, thanks to Elsevier’s generosity, five outstanding early career researchers will be supported by internationally competitive three-year fellowships. Fellows will hold the prestigious title of Hooke or Titchmarsh Fellow; Hooke and Titchmarsh are distinguished figures in the diverse history of Oxford and global mathematics.

During their time at Oxford, fellows will undertake research, develop their experience of teaching in a university environment, and work alongside academics at the forefront of the most profound advances in mathematics. By the end of their fellowships, post-holders will be independent researchers of international standing.

‘We are extremely grateful to Elsevier for this important support for Oxford Mathematics,’ says Professor Martin Bridson, Head of the Mathematical Institute. ‘Postdoctoral fellowships provide vital opportunities to researchers embarking on academic careers. Thanks to this new collaboration, five outstanding early career mathematicians will be supported as they join the institute and pursue some of the most exciting questions in mathematics.’

Finding funding in the current higher education landscape can be extremely challenging for early career researchers. Without support, many individuals struggle to establish an academic career following the end of their doctoral studies. The Mathematical Institute’s Hooke and Titchmarsh Fellowship programme, expanded by virtue of this gift, addresses this need.

Elsevier’s donation will also support a series of high-profile research meetings and workshops at the Mathematical Institute. Spread over the course of five years, the meetings will bring researchers from other UK and international institutions to Oxford in order to engage on topics ranging from data science to fundamental problems in geometry and number theory.

Professor Louise Richardson, Vice-Chancellor of the University of Oxford says: ‘I am delighted that Elsevier has chosen to work with the University’s Mathematical Institute to support our outstanding early career researchers. This initiative will not only benefit researchers here in Oxford but also the international mathematical research community. We are deeply grateful to Elsevier for their generosity.’

Ron Mobed, Elsevier Chief Executive Officer says: ‘The University of Oxford’s commitment to excellence in research, development of young and emerging talent and creating new ways of academic collaboration are very much aligned with Elsevier’s mission. It represents the future of how science should be applied to have a transformative impact on society. Research in mathematics specifically is vital to the exploration of new technologies, innovation, data science and analytics – areas in which we are investing ourselves to make research information more useful.’

Irene Fonseca: Mathematical Analysis of Novel Advanced Materials

Quantum dots are man-made nanocrystals of semiconducting materials. Their formation and assembly patterns play a central role in nanotechnology, and in particular in the optoelectronic properties of semiconductors. Changing the dots' size and shape gives rise to many applications that permeate our daily lives, such as the new Samsung QLED TV monitor that uses quantum dots to turn "light into perfect color"! 

Quantum dots are obtained via the deposition of a crystalline overlayer (epitaxial film) on a crystalline substrate. When the thickness of the film reaches a critical value, the profile of the film becomes corrugated and islands (quantum dots) form. As the creation of quantum dots evolves with time, materials defects appear. Their modeling is of great interest in materials science since material properties, including rigidity and conductivity, can be strongly influenced by the presence of defects such as dislocations. 

In this talk we will use methods from the calculus of variations and partial differential equations to model and mathematically analyze the onset of quantum dots, the regularity and evolution of their shapes, and the nucleation and motion of dislocations.

John Rognes: Symmetries of Manifolds

To describe the possible rotations of a ball of ice, three real numbers suffice.  If the ice melts, infinitely many numbers are needed to describe the possible motions of the resulting ball of water.  We discuss the shape of the resulting spaces of continuous, piecewise-linear or differentiable symmetries of spheres, balls and higher-dimensional manifolds.  In the high-dimensional cases the answer turns out to involve surgery theory and algebraic K-theory.

Oxford Mathematician Sarah Waters awarded a Leverhulme Trust Senior Research Fellowship

Oxford Mathematician Sarah Waters has been awarded a Royal Society Leverhulme Trust Senior Research Fellowship commencing this month. Sarah is an applied mathematician here in Oxford. Her interest is in physiological fluid mechanics, tissue biomechanics and the application of mathematics to problems in medicine and biology. Her work varies from classical applied mathematics problems motivated by physiological applications to highly interdisciplinary work - she collaborates with life scientists, clinicians, bioengineers, theoreticians and experimentalists to develop and solve models that are novel, realistic and provide insights into biomedical problems. The resulting models often lead to theoretical predictions that can be exploited in the laboratory.

Oxford Mathematics part of a new centre for new approaches to data science via application driven topological data analysis

Modern science and technology generate data at an unprecedented rate. A major challenge is that this data is often complex, high dimensional and may include temporal and/or spatial information. The 'shape' of the data can be important but it is difficult to extract and quantify it using standard machine learning or statistical techniques. For example, an image of blood vessels near a tumour looks very different to an image of healthy blood vessels; statistics alone cannot quantify this difference. New shape analysis methods are required.

Thanks to funding from the Engineering and Physical Sciences Research Council (EPSRC), a newly created centre combining scientists in Oxford, Swansea and Liverpool will study the shape of data through the development of new mathematics and algorithms, and build on existing data science techniques in order to obtain and interpret the shape of data. A theoretical field of mathematics that enables the study of shapes is geometry and topology. The ability to quantify the shape of complicated objects is only possible with advanced mathematics and algorithms. The field known as topological data analysis (TDA), enables one to use methods of topology and geometry to study the shape of data. In particular, a method within TDA known as persistent homology provides a summary of the shape of the data (e.g. features such as holes) at multiple scales. A key success of persistent homology is the ability to provide robust results, even if the data are noisy. There are theoretical and computational challenges in the application of these algorithms to large scale, real-world data.

The aim of this centre is to build on current persistent homology tools, extending them theoretically, computationally, and adapting them for practical applications. The Oxford team led by Heather Harrington and Ulrike Tillmann together with Helen Byrne, Peter Grindrod and Gesine Reinert is composed of experts in pure and applied mathematics, computer scientists, and statisticians whose combined expertise covers cutting edge pure mathematics, mathematical modelling, algorithm design and data analysis. This core team will in turn work closely with collaborators in a range of scientific and industrial domains.
