Tom was a pioneer in many aspects of optimization and scientific computing including combinatorial scientific computing, parallel optimization, automatic differentiation, and portfolio optimization. In addition to his influential scientific work including eight books, he was an advisor and mentor to dozens of masters, PhD and postdoctoral students. He also served in multiple leadership roles in our community, including as Director of the Cornell Theory Center and as Dean of Mathematics at Waterloo, and was awarded several honors including SIAM Fellow and the Ophelia Lazaridis University Research Chair at Waterloo. He will be greatly missed. A longer biography will appear soon on the University of Waterloo C&O department website.

Butcher, Springer 2021 https://link.springer.com/book/10.1007/978-3-030-70956-3 B-series have become an indispensable tool in the analysis of numerical methods. This monograph is by John Butcher who has developed algebraic and combinatorial analysis of numerical methods from 1963 onwards. The book contains a concise treatment of the subject including recent developments and algorithms. A virtual book launch event will be held on 11th May 2021, 09:00 British Summer Time with opening remarks given by Remi Lodh (Springer) followed by a talk on "From Runge--Kutta methods to B-series" by John Butcher chaired by Arieh Iserles. See https://jcbutcher.com/B-series-book#launch for further details and the Zoom link. ------------------------------------------------------- From: Ruth Crane [log in to unmask] Date: April 28, 2021 Subject: From Runge-Kutta methods to B-series, ONLINE, May 2021 On Wednesday, May 12, 2021, ICERM is pleased to host "From Runge- Kutta methods to B-series", a virtual lecture and Q&A with John Butcher. In the early days of Runge-Kutta methods, 1895-1901, the numerical order of particular methods was found by working out the Taylor series for the solution of a generic scalar differential equation. By comparing this with the Taylor series for the Runge-Kutta result, the order of the approximation can be found. This approach was highly successful in finding methods up to order 4 but it became more and more complicated until eventually, in the 1950s, methods up to order 6 were found. It was discovered, about that time, that the theory based on a scalar problem was not adequate, and a vector differential equation system had to be used as the test problem. The theory, arising from this high-dimensional approach, has now become B-series analysis.

Researchers from Keele University, The University of Manchester and their project collaborators are jointly organising, with ICMS, an afternoon to promote their recent research developments and to build a research/end-user community for metal detection. Sponsored by EPSRC and the Royal Society, research on the mathematical theory underpinning new developments in detecting, locating and characterising metal objects has progressed in recent years. Application areas for this technology are widespread. Areas of interest include, but are not limited to: early detection of threat objects (e.g. knives and guns) for security screening at transport hubs and public events; identification of hidden anti-personal mines and unexploded ordnance in areas of former conflict; identification of metallic objects of value in treasure hunts and in archaeological searches; non-destructive testing and determining integrity of reinforcement in concrete structures; ensuring food safety by identification of unwanted metallic contamination; scrap sorting to identify precious metals; finding hidden cables in walls and underground; discriminating between different coins in vending machines and automated checkouts. This afternoon event is our initial community building activity and will include: A series of short presentations from Keele University and The University of Manchester overviewing the research in this area; Short metal detection challenges 'pitches' by end users - followed by breakout sessions linking these challenges and the research; Discussion forum - how to support the activity going forward.

JSC operates one of the most powerful computer systems for scientific and technical applications in Europe and makes it available for research purposes to scientists at Forschungszentrum Juelich, in Germany, and throughout Europe. The goal of this project is to develop parallel-in-time integration methods with the ability to recover after hardware faults or data corruption. The approaches will be adapted to modern supercomputer architectures, also with respect to scheduling and load balancing. Also, compression techniques for reducing the memory and communication footprint will be assessed. This project is part of the EuroHPC JU project TIME-X. The ideal candidate should hold a Master's degree in the field of mathematics, computer science, engineering or a related discipline. She/he should have experience working with numerical methods and algorithms, preferably in the domain of numerical methods for time-dependent partial differential equations, as well as with writing numerical software, preferably in C++ and Python.

Both PhD projects will focus on the development and application of novel computational tools for the accurate and efficient simulation of complex multiphysics problems. While the first project is concerned with the simulation and optimization of multiphysics processes in large-scale liquid hydrogen transport, the second project focuses on the development of novel computational methods for complex multiphysics flows arising in biology and biomedicine. We are looking for highly motivated candidates with a sound background in numerical mathematics and a strong interest for developing novel numerical schemes and applying them to challenging application problems in science and engineering. Both projects require good programming skills, preferably in C++/Python/Julia, and basic knowledge in partial differential equations and their numerical solution. Knowledge/interest in fluid mechanics and/or scientific computing are considered merits. Experience with open source finite element/volume libraries such as deal.ii, mfem, dune, FEniCS, Firedrake, NGSolve, Gridap, OpenFOAM etc. are advantageous but not required. Successful candidates will be offered a three-year, full-time research position. The Department may offer a twelve month extension as a teaching assistant. The work place will be Trondheim.
