The aim of this conference is to bring together researchers working on aspects of nonlinear phenomena and to encourage interaction between experts from different areas such as Applied Mathematics, Mathematical Analysis, Fluid Dynamics, Engineering and Physics. Recent theoretical developments, new computational methods and experimental findings will be presented and discussed. We plan to avoid parallel sessions and foster as much as possible communication across the different communities. Please note all talks will be recorded and available shortly after the event for everyone who had paid and registered for the conference and will be available for one month after. Conference topics: Integrable systems and soliton theory; Nonlinear waves and nonlinear evolution equations; Dispersive hydrodynamics; Rogue waves and extreme wave phenomena; Instabilities in nonlinear media; Coherent structures and turbulence; Nonlinear phenomena in physical and biological sciences; Phenomena at the interface of nonlinear waves and machine learning. Our Oral Presentation submission is now closed. We are accepting Posters Presentations on the basis of a 200-300 word abstract until 16 June 2021. If you would like to submit a Poster please email the IMA Conferences Department with your submission. ------------------------------------------------------- From: Fabio Nobile [log in to unmask] Date: June 10, 2021 Subject: Data Assimilation and Reduced Modeling, France, Jul-Aug 2021 We are happy to announce that the CEMRACS 2021 on "Data Assimilation and Reduced Modeling for High Dimensional Problems" will eventually take place from Jul 19 to Aug 27, 2021, and registration is now open. All details available here http://smai.emath.fr/cemracs/cemracs21/index.html CEMRACS is a summer program aiming at bringing together scientists from both the academic and industrial communities to work on and discuss focused topics. The program includes a one-week summer school followed by 5 weeks of research sessions on projects proposed by academic and industrial partners. Participants may register to the summer school only or to the entire program. The summer school will be proposed in hybrid format, with participants on-site at CIRM (Luminy, France) as well as online. Due to sanitary restrictions, the number of places on-site is limited. Confirmed speakers of the summer school (Jul 19-23) are Albert Cohen, Masoumeh Dashti, Eric Moulines, Anthony Nouy, Claudia Schillings, Johannes Schmidt-Hieber. Registration is available here http://smai.emath.fr/cemracs/cemracs21/registration.html The 5 weeks research stay is fully on site at CIRM, Luminy. Interested students should apply here http://smai.emath.fr/cemracs/cemracs21/registration.html by June 19th, 2021. The number of slots for participation in the projects is very limited, but few slots are still available. ------------------------------------------------------- From: Iain Duff [log in to unmask] Date: June 10, 2021 Subject: Sparse Days 2022, Save the Date, Jun 2022 The Annual Sparse Days Meeting for 2022 will be held on 20-22 June. Normally this meeting is in Toulouse, France but we are planning to hold the meeting next year in St Girons, Ariege and to repeat the formula for the highly successful meetings held there in 1994, 2003, and 2015. Further information and confirmation of the location will be broadcast this summer but, in the meantime, please save this date. ------------------------------------------------------- From: Wim Michiels [log in to unmask] Date: June 10, 2021 Subject: Faculty Position, KU Leuven, Belgium Faculty Position, Numerical Methods for Large-Scale Inverse Problems and Data Assimilation, KU Leuven, Belgium The research unit NUMA, Department of Computer Science, invites applications for a full-time faculty position. The unit covers many aspects of numerics, incl. approximation theory, numerical integration, numerical (multi)linear algebra, numerical PDEs, uncertainty quantification, optimization and control, discrete optimization and scheduling, data science, HPC and applied numerical mathematics. The recent surge in advanced techniques for data acquisition gives rise to computational tasks of a complexity beyond numerical simulation as integrating measurement data in complex models requires specific numerical algorithms. In the simplest setting, finding the "best" model parameters given some measurement data is an optimization problem. However, demands of practical applications often go far beyond this optimization: one can, for instance, also be interested in quantifying the uncertainty on the resulting optimum, the remaining modeling error with respect to the physical system, or the evolution of the model as a function of time. The new faculty position aims to strengthen NUMA's position in scientific computing towards a data rich environment. The successful candidate is expected to develop a research program in inverse problems and data assimilation, ensure high-quality education within the area of mathematical engineering, and be prepared to provide scientific, social and administrative services.

We are looking for a mathematician (f/m/d) highly recognized in the field of applied and industrial mathematics and with special interest in applications. The professorship is embedded into the Center for Industrial Mathematics (ZeTeM). Participation in the center's leadership is desirable. The scientific focus of this professorship is preferably in the area of inverse problems, parameter identification, or mathematical methods in machine learning. The research profile should provide links to the existing research topics of ZeTeM, of the Department, as well as of the university's high-profile areas. We are searching for a personality with an excellent publication record in the fields mentioned above, who has proven her or his ability to bridge the gap between theory, applied research, and industrial practice. The appointed person will independently represent these fields in research, teaching, and applications. Experience in heading research teams, strategic planning of these teams, and, most important, in acquisition and implementation of R&D projects on national and international scale is a prerequisite. For application details, see: https://www.uni-bremen.de/en/university/the-university-as-an-employer/job-vacancies- 1/job/657?cHash=2cfd1321c07809bf6a4292d2bd5b3007 ------------------------------------------------------- From: Thomas Wihler [log in to unmask] Date: June 09, 2021 Subject: Postdoc Position, Applied and Numerical Mathematics, Univ of Bern The Mathematical Institute at the University of Bern, Switzerland, invites applications for a postdoc position in the applied and numerical mathematics group of Professor Thomas Wihler.
