The Seduction of Curves: The Lines of Beauty That Connect Mathematics, Art and The Nude. Allan McRobie's Oxford Mathematics Public Lecture now online

There is a deep connection between the stability of oil rigs, the bending of light during gravitational lensing and the act of life drawing. To understand each, we must understand how we view curved surfaces. We are familiar with the language of straight-line geometry – of squares, rectangles, hexagons - but curves also have a language - of folds, cusps and swallowtails - that few of us know.

Allan explains how the key to understanding the language of curves is René Thom’s Catastrophe Theory, and how - remarkably - the best place to learn that language is perhaps in the life drawing class. Sharing its title with Allan's new book, the talk wanders gently across mathematics, physics, engineering, biology and art, but always with a focus on curves.

Warning: this talk contains nudity.

Allan McRobie is Reader in Engineering, University of Cambridge

James Maynard appointed Research Professor and receives a Wolfson Merit Award from the Royal Society

Oxford Mathematician James Maynard has been appointed Research Professor and receives a Wolfson Merit Award from the Royal Society. The Royal Society Wolfson Merit Award is a prestigious award intended to attract or retain respected scientists of outstanding achievement and potential.

Professor Maynard's project, 'Structure in the primes, with applications', aims to develop techniques to understand the statistical properties of the distribution of prime numbers - a central problem in number theory. The project consists of three large projects to be investigated over a five-year period. The projects follow the common theme of studying classical problems in analytic number theory by attempting to classify counter-examples, should they exist. This approach has been remarkably successful in analytic arguments, and is an example of a common connection between analysis, combinatorics and algebra. The underlying techniques also provide flexible and universal means of answering rigorously many real-world questions about primes.

James Maynard is one of the brightest young stars in world mathematics at the moment, having made dramatic advances in analytic number theory in the years immediately following his 2013 doctorate. These advances have brought him worldwide attention in mathematics and beyond. Just 30, he has already gained many markers of distinction, including the European Mathematical Society Prize, the Ramanujan Prize and the Whitehead Prize. He will be an invited speaker at the quadrennial International Congress of Mathematicians in 2018. He also holds a Clay Research Fellowship (2013-18), the most prestigious early career position in world mathematics.

Thaleia Zariphopoulou appointed as a Visiting Professor in the Mathematical Institute

We are delighted to announce that Thaleia Zariphopoulou has been appointed as a Visiting Professor in the Mathematical Institute, University of Oxford for three years from 1st November 2017.

Thaleia holds the Presidential Chair in Mathematics and is the V. H. Neuhaus Centennial Professor at the University of Texas at Austin. From 2009-2012 she was the Oxford-Man Professor of Quantitative Finance here in Oxford and has remained in close contact with colleagues in the Mathematical Institute.

Thaleia's works spans financial mathematics, notably stochastic optimization and quantitative finance. She has held many visiting fellowships and in 2012 became a Fellow of the Society for Industrial and Applied Mathematics (SIAM) "for contributions to stochastic control and financial mathematics."

Oxford Mathematics introduces its new Master's in Mathematical Sciences

The Oxford Master’s in Mathematical Sciences (or 'OMMS') is now admitting students to start in October 2018.  This new master’s degree is run jointly by the Mathematical Institute and the Department of Statistics at the University of Oxford.  For the first time we are able to offer students from across the world a masters course that draws on the full range of our research across the mathematical sciences, from fundamental themes in the core to interdisciplinary applications.

This MSc complements a range of other masters’ courses at Oxford - each of which has distinctive features and meets a specialised need.  Click for further details of mathematics and statistics courses at Oxford.

Closing the Gap: the quest to understand prime numbers - Vicky Neale's Oxford Mathematics Public Lecture now online

Prime numbers have intrigued, inspired and infuriated mathematicians for millennia and yet mathematicians' difficulty with answering simple questions about them reveals their depth and subtlety.

Vicky Neale describes recent progress towards proving the famous Twin Primes Conjecture and explains the very different ways in which these breakthroughs have been made - a solo mathematician working in isolation, a young mathematician displaying creativity at the start of a career, a large collaboration that reveals much about how mathematicians go about their work.

Vicky Neale is Whitehead Lecturer at the Mathematical Institute, University of Oxford and Supernumerary Fellow at Balliol College.

How to make sense of our digital conversations

For many years networks have been a fruitful source of study for mathematicians, one of the first notable examples of network analysis being Leonard Euler's study of paths on the Königsberg bridges. Since that time the field of graph theory and network science has developed greatly and the problems we want to model have also changed. 

Perhaps the most evident modern-day networks are those of online social networks such as Facebook, Twitter, and Instagram. Unlike the networks of the Königsberg bridges which are literally set in stone, the networks of interactions and friendships between users of these networks can grow and disappear within minutes or hours. This means we need to develop new tools and algorithms to be able to analyse them fully. 

Working with the data-focused Bloom Agency, Oxford Mathematician Andrew Mellor's goal is to analyse, in real time, the conversations occurring on social media surrounding brands, ideas, and reaction to real world events and television shows. To do this he developed the temporal event graph, a static representation of a temporal network. In the temporal event graph our interactions are now nodes, and interactions are linked if they share participants and occur close together in time. Looking at temporal networks in this way captures both the topology of the interactions between agents and the timings between these connections. This complex interplay between topology and temporal connectivity has a profound effect on the spread of epidemics (or viral content) on the network. We can use methods derived for static networks to efficiently analyse the network. These methods are not restricted to the digital domain and can in fact be applied to any sequence of interactions such as flight and transport networks, brain networks, and proximity networks.

Returning to the original application, Andrew and colleagues are currently using the temporal event graph to understand how conversations evolve online, how a user's behaviour changes depending on the conversational topic, and to classify the zoo of conversation types that have been observed. This gives a unique insight into how we behave online, and gives new methods of characterising behaviour as a function of time.
