The paper “Geometric invariants of the horizontal velocity gradient tensor and their dynamics in shallow water flow” has been accepted for publication in the Quarterly Journal of the Royal Meteorological Society.  The authors are Ian Roulstone, Andy White and Sid Clough.  Sid Clough is a Senior Fellow in Mathematics at Surrey, and Andy White is a […]

Peter Hydon has delivered his new book, Difference Equations by Differential Equation Methods, to Cambridge University Press for publication. Around twenty years ago, an eminent numerical analyst said, “Any problem involving difference equations is an order of magnitude harder than the corresponding problem for differential equations.” Research since that time has transformed our understanding of difference […]

Gianne Derks has been awarded a grant from the Dutch mathematics cluster “Nonlinear Dynamics in Natural Systems” (NDNS+).  The grant funds a 3-month visit to Leiden starting in mid-February.  Gianne will be visiting the Mathematical Institute and the Leiden Academic Center for Drug Research at the University of Leiden. She will work with Arjen Doelman, […]

On 13th January 2014, Annegret Burtscher, a joint Ph.D. student of James Grant (Surrey) and Prof. P.G. LeFloch (Paris 6 University), successfully defended her Ph.D. at the University of Vienna. Her thesis is on “Analytic and geometric aspects of spacetimes of low regularity“, and she presented her work on energy estimates for tensor fields under […]

Sergey Zelik is in Moscow this week to attend the conference “Attractors, Foliations and Limit Cycles“.  The conference is taking place at the Independent University of Moscow from 13 to 17 January.  The conference is celebrating the 70th birthday of Yulij Ilyashenko.  The main topics of the conference are (a) limit cycles and Hilbert’s 16th […]

Kostas Sfetsos is visiting the Theoretical Physics Research Group at the University of Swansea this week.  He is external examiner for a PhD thesis, and then on Friday 17 January he is giving seminar on “A new line of integrable deformations“.  New integrable models having a rich group theoretical structure and interpolating between exact Conformal […]
