The BECMC will be held on 15th-16th July 2021 at the University of Birmingham. This will be a two-day event aimed at PhD students and early career mathematicians. It offers participants a valuable opportunity to network with others in their field, gain an insight into the active areas of research in a wide range of mathematical disciplines, and give a talk in a relaxed and friendly environment. The deadline for submission of abstracts will be the 14th May 2021 with the deadline for registration being the 25th June 2021. (For more details, please visit http://web.mat.bham.ac.uk/BYMC/BECMC21/). Given the current government roadmap out of lockdown, the BECMC is provisionally organised to be held in person with all relevant COVID-19 guidelines being implemented. However, this may be subject to change depending on future government announcements. We therefore encourage people not to book travel or accommodation until at least the 1st June 2021, at which point the final easing of lockdown restrictions should be made clear. The committee recognises that the standard of access at academic conferences across the UK is largely unacceptable. Our team are working to improve this, both for this BECMC 2021 and for future conferences. Please see our website for full details about accessibility at the conference.

The ever increasing importance of methods originating in statistical inference and their growing use at large cloud computing facilities leads both the scientific and HPC communities to look into new ways of applying computational steering and incorporate it into their large-scale simulations. The SDASC workshop will feature automated data analysis efforts at the convergence of computational science, HPC, large-scale data analytics and inference. The focus will be on the integration of the HPC techniques and statistical learning tasks into the modern software stack of computational science. The submission deadline is April 29, 2021 (AoE) The workshop will be held virtually. More details about the virtual realization of the workshop, the inclusion of accepted papers in the conference proceedings, and a list of topics is available at: SDASC web site: https://sdascconf.github.io/ ------------------------------------------------------- From: Ratnasingham Shivaji [log in to unmask] Date: April 18, 2021 Subject: UNC Greensboro PDE Conference, ONLINE, Jul 2021 We are excited to inform you that we are initiating a conference series in partial differential equations.

The fellowship is for two years full-time with starting date September 1, 2021, or by agreement. Project description: Stochastic optimization plays a key role in data driven decision making, where problems are often high-dimensional and of black-box nature. The focus of this project is to develop new theory and algorithms for the area, with a potential emphasis on stochastic derivative-free algorithms that combine dimensionality reduction and stochastic optimization. As an application, the applicant will interact with a multidisciplinary research team focused on optimizing the ambulance care in Sweden. A digital twin of the ambulance care has been developed and through large scale simulations the performances of different resource allocations (location and scheduling of ambulances) can be predicted. Given some economical and practical constraints the overall aim is to find the best resource allocation. The appointed candidate will get the opportunity to carry out collaborative research according to a mutually agreed research plan. The postdoc will become a part of the research group in mathematical statistics and be offered the opportunity to present the research at international conferences and to participate in joint workshops and seminars. This postdoctoral fellowship is financed by The Kempe Foundations and amounts to 312 000 SEK per year.

It is the goal of this position to explore the connection between mechanical deformations of solids and reaction-diffusion processes via partial differential equations. The range of problems includes consistent modeling of this connection for specific applications (e.g. in semiconductor theory or growth of biological tissue), the mathematical wellposedness (existence and properties of solutions) via functional analytical methods, and the derivation of effective models. We are looking for candidates with a master's degree in mathematics and a strong background in applied analysis. In particular, a very good knowledge in the area of partial differential equations and functional analysis is required. Prior knowledge in the calculus of variations, continuum mechanics and/or the modeling with partial differential equations is beneficial. A willingness to work interdisciplinary with researchers from different fields (e.g. physics or biology) is also desirable.

The aim of the Ph.D. thesis is to develop some new numerical methods to simulate Bose-Einstein condensates that play a crucial role in quantum mechanics. These numerical methods will be developped for both stationnary states and for the dynamics of the wave function, in dimensions 2 and 3. In particular, we will consider the multi-components case and the integration of nonlocal nonlinear interactions. The implementation of the methods will be made in Python first and then integrated in the BEC2HPC parallel solver to provide efficient methods for physics applications considered at the end of the Ph.D thesis. The ideal candidate has a Master Degree in applied mathematics, computational mathematics or computational engineering/physics. The Ph.D. position is funded for three years in an international context since the candidate will have to spend half of his/her time between Nancy (France) and Chengdu (China). For this reason, the candidate must be able to speak/write english correctly. Applications must be submited at: http://doctorat.univ-lorraine.fr/fr/les-ecoles-doctorales/iaem/offres-de-these/methodes- numeriques-rapides-et-precises-pour-l\ a Please contact the two advisors for further informations: Xavier ANTOINE ([log in to unmask]) ; Qinglin TANG ([log in to unmask]) ------------------------------------------------------- From: Laurette Lauffer [log in to unmask] Date: April 22, 2021 Subject: PhD Position, Numerical Analysis of Multiscale Methods, KIT Seeking a Doctoral Researcher (f/m/d - 75 %) for the CRC 1173 doctoral thesis project "Numerical analysis of multiscale methods". The Collaborative Research Center "Wave phenomena - analysis and numerics" (CRC 1173) of the Karlsruhe Institute of Technology, is currently seeking to recruit, as soon as possible, limited to three years, a doctoral researcher (f/m/d - 75%). Nowadays a lot of new materials are artificially constructed and tailored to exhibit astonishing physical properties. These metamaterials are characterized by fine structures of different material components. Within mathematical models, this leads to partial differential equations with a coexistence of multiple spatial scales. However, standard numerical methods need to resolve all fine scales and thus have a prohibitive computational effort. Numerical multiscale methods in turn decompose the solution into a macroscopic and a fine-scale contribution allowing for an efficient approximation of the macroscopic solution on coarse meshes. In the project Numerical analysis of multiscale methods (https://www.waves.kit.edu/AP5.php), we develop such schemes and prove a priori estimates for the discretization error. A main objective of this project is to develop and analyze multiscale methods for problems with nonlinearities, random perturbations, or multiscale dynamics. More details about the position can be found here: https://www.waves.kit.edu/joboffers.php . Applicants should have: Excellent Master or an equivalent degree in Mathematics. Strong background in numerical methods for partial differential equations and numerical analysis. Programming skills (in MATLAB, python or C++) are beneficial. We expect good writing and oral communication skills in English along with the ability to work independently within an international team. Applications should include a cover letter, a curriculum vitae, a statement of research interest, contact information for two referees, and copies of degree certificate(s).
