We have listed and analyzed them in the Open-Access paper Claude Brezinski, F. Alexander Norman, M. Redivo-Zaglia The legacy of Peter Wynn Mathematics 2021, 9, 1240. https://doi.org/10.3390/math9111240 A web site on Wynn has been constructed at the University of Texas at San Antonio https://mathresearch.utsa.edu/Legacy/Peter-Wynn/ It contains a small biography, a list of Wynn's publications, a bibliography on the topics treated, photos, and all the unpublished papers of Wynn which can be freely downloaded. These papers cover extrapolation and acceleration, Pade and rational approximation and interpolation, continued fractions, complex analysis, abstract algebra, and other topics. They can be freely exploited to start new research. We offer them to the international community of mathematicians. The papers and reports published by Wynn during this lifetime are analyzed in the book: Claude Brezinski, Michela Redivo-Zaglia Extrapolation and Rational Approximation The Works of the Main Contributors Springer Nature, Cham, Switzerland, 2020 https://www.springer.com/us/book/9783030584177 Claude Brezinski, F. Alexander Norman, M. Redivo-Zaglia ------------------------------------------------------- From: Serge Gratton [log in to unmask] Date: June 02, 2021 Subject: Oleg Burdakov It is a sad duty to let you know that Oleg Burdakov has passed away on the night of June 1-2, 2021, after courageously fighting illness for many months. Beyond his well-known scientific achievements and his important role as the founder and EIC of Optimization Methods and Software, Oleg will be remembered as a lively, enthusiastic colleague, always open to new ideas and willing to promote them. Many of his friends will regret his wonderful sense of humour and love of life. We express our deepest sympathy to Galya and Dasha, his wife and daughter, whom many of us have met and appreciated. Good bye dear Oleg, we will not forget you. Serge Gratton and Philippe Toint ------------------------------------------------------- From: Kris ONeill [log in to unmask] Date: June 02, 2021 Subject: New Book, Numerical Linear Algebra and Optimization Numerical Linear Algebra and Optimization by Philip E. Gill, Walter Murray, and Margaret H. Wright This classic volume covers the fundamentals of two closely related topics: linear systems (linear equations and least-squares) and linear programming (optimizing a linear function subject to linear constraints). For each problem class, stable and efficient numerical algorithms intended for a finite-precision environment are derived and analyzed. While linear algebra and optimization have made huge advances since this book first appeared in 1991, the fundamental principles have not changed. These topics were rarely taught with a unified perspective, and, somewhat surprisingly, this remains true 30 years later. As a result, some of the material in this book can be difficult to find elsewhere. 2021 / xxii + 426 pages / Softcover / 978-1-611976-56-4 / List $89.00 / SIAM Member $62.30 / CL83 Link to book: https://my.siam.org/Store/Product/viewproduct/?ProductId=38118492 ------------------------------------------------------- From: Nick Higham [log in to unmask] Date: June 01, 2021 Subject: Celebrating 70th Birthday of Jack Dongarra, ONLINE, Jul 2021 New Directions in Numerical Linear Algebra and High Performance Computing: Celebrating the 70th Birthday of Jack Dongarra, July 7-8, 2021, University of Manchester.

Its goal is to establish a testbed based on the operational system of the German Weather Service (DWD) to explore potential improvements to weather prediction through machine learning. Current weather predictions still suffer from systematic errors and weather services around the world are now realising that circumventing these deficits through machine learning could revolutionise the discipline in the next decades. This requires a fundamental rethinking, interlinking meteorology much better with mathematics and computer science. We seek an ambitious postdoctoral researcher with an interest in mathematical and computational challenges of machine learning and its combination with numerical weather prediction. Main tasks of the position are to analyze the fundamental mathematical characteristics of the envisioned new testbed, to develop a strategy for optimisation using machine learning methods and to quantify forecast uncertainty. More details about the position can be found here: https://s.kit.edu/z1jhmyzk Applicants should have: PhD in Mathematics, Computer Sciences or closely related subject; Strong background in numerical analysis, statistics or mathematical aspects of machine learning; Programming skills (e.g. python, MATLAB, C++, R); the ability to work within an interdisciplinary team. Please apply via E-mail to Dr Barbara Verfurth [log in to unmask] until 23/06/2021 including a detailed CV, scans of degree certificates, a letter of motivation, contact information for two referees. Planned start date is 01/09/2021. ------------------------------------------------------- From: Paul Ledger [log in to unmask] Date: June 01, 2021 Subject: Postdoc Position, Keele Univ, UK We have open 3 year RA (post-doctoral) position at the School of Computing & Mathematics, Keele University (UK) on a new EPSRC funded project with Department of Mathematics, The University of Manchester (UK).
