The article “How math helped forecast Hurricane Sandy – the mathematics of predicting a hurricane’s path“, authored by John Norbury (Oxford) and Ian Roulstone, has been published this month in Scientific American.   Many early forecasts for Hurricane Sandy last year predicted that the system would fizzle over the Atlantic. Yet a model developed by researchers […]

Ian Roulstone, in collaboration with John Norbury (Oxford), has an article on the Huffington Post Blog on 19 July, giving the mathematics behind the heat wave. A heat wave in the UK is usually measured by temperatures reaching in excess of 30 degrees Celsius for more than a week.  The current heat wave – the […]

 The paper of Philip Aston and Neil Bristow on “Alternating period doubling cascades” has been accepted for publication in Nonlinearity.  In the paper, they consider period-doubling cascades in two-dimensional iterated maps in which forward and backward period-doubling bifurcations alternate to form an alternating period-doubling cascade. By tracking the eigenvalues of a typical map through such […]

Elyse Rogers, an undergraduate in mathematics, is doing a summer project, supervised by James Grant, on the topic of “Gravitational collapse in General Relativity“, with the following description: ‘The project will investigate simple models of systems undergoing gravitational collapse to form black holes within General Relativity, Einstein’s classical theory of gravity. Specifically, the project will […]

Ying Huang, an undergraduate in mathematics, is doing a summer research project, supervised by Philip Aston, on the topic of “Reconstruction of Attractors for Blood Pressure Data as a Diagnostic Tool“, with the following description: ‘Collaborators at Kings College have collected data on the blood pressure of a mouse (undisturbed in a cage) 1000 times […]

Alessandro Torrielli’s paper on “The all-loop integrable spin-chain for strings on AdS_3 x S^3 x T^4: the massive sector” has been accepted for publication in the Journal of High-Energy Physics.  The co-authors are Riccardo Borsato (Utrecht), Olof Ohlsson Sax (Utrecht), Alessandro Sfondrini (Utrecht), and Bogdan Stefansks (City U, London).  In the paper they bootstrap the […]
