We were unable to find some of his publications. If some of you have them, could you send them to me by post-office mail or, preferably, by electronic mail (any form). These references are P. Wynn, On some extensions of Euclid's algorithm, and some consequences thereof, Report CRM, Centre de Recherches Mathematiques, Universite de Montreal, 1972. P. Wynn, An array of functions, Report, School of Computer Science, McGill University, Montreal, 1976. P. Wynn, A continued fraction transformation of the Euler-MacLaurin series, Report, School of Computer Science, McGill University, Montreal, 1976. In our paper, we also intend to post testimonies by reseachers whose work was influenced by the work of Wynn. If this is your case, could you send us a text (preferably in latex) describing your work, how it is connected to Wynn's work, and how you used and/or extended it (references can be inserted). Any personal testimony or anecdote on him is also welcome. Of course, you also have to allow us to publish your contribution in our paper, where it will be acknowledged. Thank you and best regards.

Frédéric Bonnans [log in to unmask] Date: May 14, 2019 Subject: New Book, Convex and Stochastic Optimization Convex and Stochastic Optimization Bonnans, J. Frederic 2019 / xiii + 311 pages / Softcover / 978-3-030-14977-2 / Springer Nature / List $59.99 This textbook provides an introduction to convex duality for optimization problems in Banach spaces, integration theory, and their application to stochastic programming problems in a static or dynamic setting. It introduces and analyses the main algorithms for stochastic programs, while the theoretical aspects are carefully dealt with. The reader is shown how these tools can be applied to various fields, including approximation theory, semidefinite and second-order cone programming and linear decision rules. This textbook is recommended for students, engineers and researchers who are willing to take a rigorous approach to the mathematics involved in the application of duality theory to optimization with uncertainty.

Flows involving solid particulates are ubiquitous in nature and industry alike. Such flows are found in pharmaceutical production, the chemical industry, the food and agricultural industries, energy production and the environment. Many unsolved problems remain, however. In order to be able to solve problems, granular flows need to be understood so that their behaviour can be controlled and predicted. We are able to describe rapid granular flows, where the particles are highly agitated and there has been some success describing static systems. The intermediate regime, where these two phases meet and coexist, is not as well understood and yet is the most commonly observed behaviour of granular flow. The objective of this meeting will be to interface the two ends of the particulate flow spectrum - those working to understand the fundamentals of granular flows and those attempting to control particulate flows in an industrial setting - to develop solutions to the complex problems presented by dense granular flows. Themes will include dense granular flow, biological systems, self- propelled particles and geological flows, exploring new developments in theoretical analysis and experimental techniques. All attendees will be provided with an opportunity to present recent work and there will be substantial time for discussion, both during the workshop and during the evening! Postgraduate and PhD students are particularly welcomed and oral presentations will reflect the breadth of the field. Registration is now open via https://my.ima.org.uk/ For further information on this conference, please visit: https://ima.org.uk/10275/3rd-ima-conference-on-dense-granular-flows ------------------------------------------------------- From: Iain Duff [log in to unmask] Date: May 17, 2019 Subject: Sparse Days 2019, France, Jul 2019 The Annual Sparse Days meeting will be held at CERFACS in Toulouse on 11 and 12 July 2019. The deadline for registration is 14th June using the web site https://sparsedays.cerfacs.fr/en. As usual, there is no registration fee but interested parties should register using the website. Please do register before the 14th June since it will greatly help our organization. When you register, you should indicate whether you want to give a talk and whether you want to attend our traditional conference dinner on the evening of Thursday 11th. The dinner will be held at Les Caves de la Marechale (free of charge for students, 22 euros for non-students, 43 euros for extra guests). The normal length for the talk and questions is 30 minutes but this is open to negotiation in either direction subject to the fact that as usual we will not be having parallel sessions. For participants wanting to go to the ICIAM meeting in Valencia there is a summer scheduled flight on Easyjet that flies non-stop to Valencia leaving Toulouse at 11.45 on Sunday 14th. If you are worried about your carbon footprint there is a regular train service or you can drive; both options taking around 7.5 hours. ------------------------------------------------------- From: Carlos J.

Interested persons are encouraged to consult the web sites below. There may be limited support for early career researchers; this can be requested at the same time as the application to attend. The workshop forms part of a bigger programme, namely Complex Analysis: Techniques, Applications, and Computations, which runs from 2 September to 19 December. See https://www.newton.ac.uk/event/cat for details of the specific programme, and https://www.newton.ac.uk/events/how-to-participate for various ways in which to participate (including two other workshops on different aspects of applied complex analysis.) ------------------------------------------------------- From: Shawn W. Walker [log in to unmask] Date: May 14, 2019 Subject: Numerical Methods for Extended Liquid Crystalline Systems, USA, Dec 2019 Liquid crystals (LCs) are classic examples of partially ordered materials that combine the fluidity of liquids with the long-range order of solids, and have great potential to enable new materials and technological devices. A variety of LC phases exist, e.g. nematics, smectics, cholesterics, with a rich range of behavior when subjected to external fields, curved boundaries, mechanical strain, etc. Recently, new systems came into focus, such as bent-core LC phases, twist-bend-modulated nematics, chromonics and polymer-stabilized blue phases, with more to be discovered. Best known for applications in displays, LCs have recently been proposed for new applications in biology, nanoscience and beyond, such as biosensors, actuators, drug delivery, and bacterial control (related to active matter). Indeed, it is believed that the LC nature of DNA once enabled the mother of all applications, namely life itself. New numerical methods and scientific computation is needed to guide new theory and models for these systems that capture the interplay of symmetry, geometry, temperature and confinement in spatio-temporal pattern formation for LCs and extended LC-like systems. This workshop provides an interdisciplinary platform for computational and experimental research in extended LC-like systems, and how these approaches can yield new theoretical insight for novel LC systems.

In other case, you can submit your work following the instructions given in our website http://mate.dm.uba.ar/~bail2020/submissions.html. Buenos Aires, the capital of Argentina, has a varied architecture, reflecting a mixture of Spanish, French and Italian styles. Its culture, cosmopolitan nature, the fact that it is avant-garde and at the same time traditional, make Buenos Aires a very friendly city as modern as it is conservative. Buenos Aires has a music that distinguishes it world wide, Tango, together with a very rich cultural movement. Asides from that, Buenos Aires is also known as a city with a varied and attractive gastronomic offer, multiple shows and a great night life.
