Subject: British Early Career Mathematicians, UK, Jul 2021

Registration and abstract submissions are now open for the British
Early Career Mathematicians' Colloquium (BECMC) (formerly BYMC).

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.

Subject: Postdoc Position, Optimization of High-dimensional Systems

The Department of Mathematics and Mathematical Statistics at Umea
University is seeking a postdoctoral fellow in optimization of high-
dimensional systems with applications to ambulance care. 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.

Subject: PhD Position, Applied Mathematics (Analysis), WIAS (Berlin)

WIAS invites applications for a PhD student position (f/m/d)
(Ref. 21/11) in the Research Group "Partial Differential Equations"
(Head: Professor Alexander Mielke) starting as soon as possible.

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.

Ph.D. position "Accurate and efficient computational methods for the
HPC simulation of Bose-Einstein Condensates"

We are offering a three-years funded PhD position in applied and
computational mathematics jointly between the Institut Elie Cartan de
Lorraine (Universite de Lorraine, France) and the department of
mathematics of Sichuan University (China).

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:

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). Please apply online via
[log in to unmask] until May 28, 2021.  For further information,
please contact Dr. Barbara Verfurth, [log in to unmask], or Ms
Laurette Lauffer, [log in to unmask]
