After gaining a first class degree in Mathematical Sciences from the University of Edinburgh in 1964 and a PhD from Australian National University under the supervision of Mike Osborne, Alistair moved to Dundee in 1969, first on a Fellowship and then as a Lecturer. He made substantial contributions to Numerical Analysis throughout his career. He took over the organisation of the Dundee Biennial Numerical Analysis Conferences from John Morris in 1977 and we shared the duties from 1985 to 2007. Alistair published extensively, including a text book on Approximation Theory and another on matrix eigenvalue problems. With his relaxed style and gentle sense of humour he was much in demand as a conference and seminar speaker. As well as being co-editor of the IMA Journal of Numerical Analysis from 1989 to 2004 he was an Associate Editor for many other journals. He was elected a Fellow of the Royal Society of Edinburgh in 1996. He also served two periods as head of the Mathematics Division, a role he carried out with great calmness and vision. He will be sorely missed by all his friends and former colleagues. Alistair was diagnosed with asbestos-related lung cancer in the Spring of this year. Until his last few days he was cared for at home by his wife, Hilary, and daughter, Kirsty. ------------------------------------------------------- From: JAC Weideman [log in to unmask] Date: August 13, 2019 Subject: Dirk Laurie (1946-2019) Dirk Pieter Laurie (1946-2019) It is with great sadness that we report that Dirk Laurie passed away on August 10, after struggling with his health the past six months or so. A student of AR (Ron) Mitchell, Dirk graduated with a Ph.D. from the University of Dundee in 1977. He was a researcher at the National Research Institute for Mathematical Sciences in South Africa, and held chairs at the Potchefstroom University for Christian Higher Education (these days Northwest University), as well as Stellenbosch University. Dirk made significant contributions to a number of areas in numerical analysis, including quadrature and linear algebra. He was one of five solo- winners of the SIAM 100-digit challenge of 2002 and a co-author of the related bestselling book. One of his passions was the South African Mathematics Olympiad, and he accompanied the national team on several occasions to the IMO. Outside of mathematics, his interests were numerous: Chess (South African schools champion), music (choir singing, playing the recorder, and general aficionado), cryptic crosswords (both their compilation and their physical outlay by the LaTeX package he created), and puzzle solving in general. In his younger days, he was a familiar face on South African television, where he participated in general knowledge quiz shows and also served as a pundit during elections. Up to his death, Dirk was editor- in-chief (and founding member) of the first online journal for scientific research papers published in Afrikaans, a language he was passionate about. Dirk is survived by his wife, Trienke, and five sons.

At this time, we are seeking pre-proposals for host locations outside of the United States. CSE is a biennial meeting that has become SIAM's largest meeting, with roughly 2,000 attendees expected for CSE21. Details on previous CSE meetings can be found at the SIAG/CSE's wiki at http://wiki.siam.org/siag-cse . Hosting CSE23 provides a vital service to the international computational science & engineering and SIAM communities. Most recent and upcoming SIAM conferences held outside of the US and Canada have involved a local institution taking financial responsibility, with SIAM providing various program management and marketing services for a fee. In addition to this model, SIAM welcomes pre-proposals from institutions interested in alternative models, including those where SIAM takes full financial responsibility and those where SIAM and a local institution share the risk and revenue. Pre-proposals will be examined by the SIAG/CSE officers and SIAM, who will then issue invitations for detailed proposals. The final decision is expected to be made in the January 2020 time period. Further information and requested preproposal content can be obtained from the SIAG/CSE officers and SIAM's Director of Programs and Services, Richard O. Moore . Pre-proposals are due by October 1, 2019 (no extensions) to the SIAG/CSE program director at [log in to unmask] .

This project involving several biology laboratories, aims at studying the impact on oyster culture of fields of wind turbines. We study graph models for ecosystems. First, we will study static models corresponding to flow models in graphs typically studied in operations research. The problem is orignal because these flows (CO2 exchanges) are difficult to measure in situ; we would like to estimate the values carried by the edges of the graph following different criteria, study the polyhedron of feasible solutions and identify an objective function (which is not known). In a second phase we will consider dynamical models, i.e. ordinary differential equations involving the graph Laplacian. Computations will first be done on a local LMI server and then on the servers of the CRIANN computing center of Normandie. Keywords: graphs, flows, polyhedra, optimisation, modelling, dynamical systems. Duration : 8 to 12 months with possible renewal starting in the fall of 2019 Salary : about 2200€/month Background of the candidate : We expect a solid training in applied mathematics, computer science or operations research (good level M5/ engineering degree or doctorate). The research scientist will have the opportunity to participate in the development of models with the team of researchers. He will implement these models on a work station dedicated to the project. He should have one or several experiences of code development for scientific computing. Know-how in parallel computing would be a plus. Finally, we will encourage the research scientist to present the results in scientific conferences and co-author research articles.

This newly established scholarly journal, provided on a Fair Open Access basis - without cost to both readers and authors, see below - disseminates peer-reviewed articles in all aspects of nonsmooth analysis relevant to optimization and equilibrium problems such as (but not limited to) analysis of infinite-dimensional algorithms for nonsmooth optimization and equilibrium problems, in particular in function spaces, necessary and sufficient optimality conditions based on generalized derivatives, sensitivity and stability properties - including regularization theory - of nonsmooth optimization and equilibrium problems, solution properties such as preservation of continuity or discontinuity properties of problem data, problem reformulations such as convex relaxation and lifting, optimization of variational inequalities and nonsmooth equations, bi- and multilevel optimization, robust and chance-constrained optimization. Papers focusing on applications (e.g., optimization in data science or energy markets) are also welcome if the results are of broader interest beyond application specialists and contain mathematical insights (either analytical or algorithmic) that are relevant for other applications as well. The journal also expressly invites works of an expository nature. The full list of editorial board members can be found under https://jnsao.episciences.org/page/editors As a Fair Open Access journal, it is owned and controlled by the scholarly community independent of commercial publishers, authors retain copyright of their works, which are published under a standard open access license as outlined in the editorial policy, and all articles are made freely available to the public without any cost to authors in the form of an arXiv overlay journal.
