At the end of February, Philip Aston visited Sao Paulo for the start of the UGPN funded collaboration between researchers at Sao Paulo, North Carolina State University (NCSU) and Surrey investigating mathematical modelling of hepatitis C infection. Hien Tran and Tom Banks from NCSU were also visiting and they had good discussions with Aluisio Segurado […]

The paper “Stability under Galerkin truncation of A-stable Runge-Kutta semidiscretizations in time“, by Marcel Oliver and Claudia Wulff has been accepted for publication in the Proceedings of the Royal Society of Edinburgh, Section A: Mathematics. The paper considers semilinear evolution equations for which the linear part is normal and generates a strongly continuous semigroup and […]

Wednesday 13 March is the date of the UK launch of the book “Invisible in the storm: the role of mathematics in understanding weather”.  The authors are John Norbury (Oxford) and Ian Roulstone, and the publisher is Princeton University Press.  It is the first book to recount the history, personalities, and ideas behind one of […]

Bin Cheng visited the University of Reading on Tuesday 12 March and gave a talk in the Mathematics Seminar Series.  The title of the talk was “Analysis of some nonlinear PDEs from multi-scale geophysical applications” with abstract: the talk is about systems of PDEs from geophysical fluid dynamics with multiple time scales, in which linear […]

The paper “Computing the invariant measure and the Lyapunov exponent for one-dimensional maps using a measure-preserving polynomial basis“, by Philip Aston and Oliver Junge (TU Munich) has been accepted for publication in the journal Mathematics of Computation.  The paper considers a generalization of Ulam’s method for approximating invariant densities of one-dimensional chaotic maps.  Rather than […]
