Werner Bauer attended the European Geophysical Union 2024 General Assembly which was held in Vienna from 14-19 April. The EGU generally attracts over 15,000 onsite participants from over 100 countries as well has virtual participants. Werner was convenor of the session on “Advances in Numerical Earth System Modeling: Identifying Systematic Errors and Charting Innovative Approaches to Enhance Numerical Weather and Climate Prediction” which had 9 speakers (link here for session website). He also presented a poster, co-authored with Colin Cotter (Imperial), on “Accurate solutions of hig ..read more

Tom Bridges visited Northumbria University in Newcastle-upon-Tyne this week (1-2 May). He visited the Mathematics of Complex and Nonlinear Phenomena Group, and his hosts were Antonio Moro and Dan Ratliff. He gave an MCNP seminar on Wednesday on “Stability of solitary waves and fronts in Hamiltonian PDEs“. A screenshot of his opening slide is shown below ..read more

The paper “Comparison of Traditional and Hybrid Forms of Optimal Localisation for Mitigation of Sampling Error in Ensemble Kalman Filters“, co-authored by Rebecca Atkinson, (former PhD student at Surrey) Jonathan Flowerdew (UK Met Office), Sue Hughes (Engineering, Surrey), and Ian Roulstone, has been published in Tellus. The paper is published open access and freely available (link here). The screenshot below shows Figure 1 from the paper ..read more

The paper “Smooth extensions for inertial manifolds of semilinear parabolic equations“, co-authored by Anna Kostianko (Zhejiang Normal University) and Sergey Zelik, has been published in Volume 17 of “Analysis and PDEs“. The paper is published open access (link here). The paper is devoted to a comprehensive study of smoothness of inertial manifolds (IMs) for abstract semilinear parabolic problems. The paper shows, under natural assumptions, that the obstacles to the existence of a C^n-smooth inertial manifold (where n is any given number) can be removed by increasing the dimension and by modif ..read more

Dario Izzo, a PhD student in the Surrey Space Centre, jointly supervised by Nicola Baresi (Surrey Space Centre), Giacomo Acciarini (European Space Agency) and David Lloyd, gave a talk at the 29th International Symposium on Space Flight Dynamics (link here). The ISSFD is a series of conferences (link here) providing an international forum for specialists in the field of space flight dynamics. The 2024 event took place 22-26 April in Darmstadt, Germany. Dario spoke on Thursday in the session on “Orbit Theory”. The photo below shows Dario giving the talk, and includes the title ..read more

The paper “Generative AI model shows fake news has a greater influence on elections when released at a steady pace without interruption“, authored by Dorje Brody, has been published in The Conversation (link here). It is not clear that disinformation has, to date, swung an election. But there is a strong sense that it has had a significant impact, nonetheless. To study this problem, a generative model becomes handy because it can create many histories. A generative model is a mathematical model for the root cause of an observed event, along with a guiding principle that tells you in which way ..read more

Anne Skeldon is visiting the Department of Mathematics at the University of Manchester this week (15-16 April) for a Workshop on “Dynamics and Piecewise Smooth Systems: what’s new?” Anne is giving the closing lecture, which is also the Departmental Heilbronn-sponsored Seminar, on the topic of “The slow-fast dynamics of sleep regulation“. Her talk is based on the paper “Creation of discontinuities in circle maps” (link here) co-authored with Gianne Derks (Leiden) and Paul Glendinning (Manchester). The screenshot below is from Figure 1 in the paper ..read more

Michael Henderson, a Principal Research Scientist at the IBM Research Center in New York (link here), is visiting the Mathematics Department this week (15-19 April), for research interaction, and to give a talk. His hosts for the visit are Tom Bridges and Imran Nasim. He is working with Imran on machine learning and scientific computing, and meeting with a range of other staff on parameterisation of multi-dimensional manifolds. His talk on Friday 19 April in the Friday Mathematics Seminar is on “Continuation for point clouds which represent smooth manifolds“. The photo below shows Imran, Micha ..read more

Paul Bergold and Cesare Tronci are in Germany this week (8-12 April), visiting the Chemistry Department at the Goethe University in Frankfurt. They are there for a research project meeting with Prof Dr Irene Burghardt (co-I on their Leverhulme project). Their collaborator Prof Rocco Martinazzo from the Universita’ Statale di Milano also attended. The photo below shows the team on the university campus (left to right: Rocco, Cesare, Irene, Paul ..read more

David Lloyd is in the Netherlands this week (8-12 April) visiting the Mathematics Institute for research interaction with Gianne Derks (Leiden, and ex-Professor at Surrey), and Peter van Heijster (Wageningen). The photo below shows that team during a break in the action ..read more
