Subject: Workshop on Asynchronous Many-Task Systems and Applications (WAMTA) 2026
The objectives of the WAMTA workshop series are to bring together
experts in asynchronous many-task frameworks, developers of science
codes, performance experts, and hardware vendors to discuss the
state-of-the-art techniques needed to program, analyze, benchmark, and
profile these codes to achieve maximum performance possible from
modern machines. This workshop will promote a dialogue between these
communities, and help identify challenges and opportunities for
advancement in all the disciplines they represent.
WAMTA 2026 will take place at the Max Planck Computing and Data
Facility at the research campus Garching near Munich (Germany),
February 16-18, 2026.

Subject: Equadiff 2026, Prague, Czech Republic, Jun 29-Jul 3, 2026
Equadiff 2026, the 16th Czechoslovak Equadiff, will be held in Prague,
Czech Republic, from June 29 to July 3, 2026. It is the latest in a
series of biennial European conferences on differential equations and
their applications, one of the oldest active series of mathematical
conferences held periodically since 1962.
The conference will be devoted to the fields of ordinary differential
equations, partial differential equations, as well as numerical
analysis and applications. These topics will be covered by plenary and
invited lectures, minisymposia, contributed talks, and posters.
Confirmed plenary speakers:

Subject: MATHRIX Assistant Professorships in Mathematics at University of Münster, Germany
The Cluster of Excellence Mathematics Münster: Dynamics – Geometry –
Structure at the University of Münster invites applications for two
MATHRIX Assistant Professorships in Mathematics (Salary level W1)
see https://uni.ms/mathrix
One of the positions will be filled in an area of theoretical, and one
in an area of applied mathematics. The professorships are for three
years with the possibility of an extension for another three years
upon positive evaluation. Applications are particularly welcome if
they strengthen, complement and/or connect existing research topics of
the cluster. Successful candidates should contribute to existing
and/or future third-party funded grants. The professorships should
contribute to gender equality within the mathematical sciences, which
might for example be documented by an appropriate gender equality
concept. Applicants must hold a doctoral degree in mathematics or in
a nearby discipline. They should demonstrate a strong research record
and appropriate teaching experience. The University of Münster
strongly supports equal opportunity and diversity. We welcome all
applicants regardless of sex, nationality, ethnic or social
background, religion or worldview, disability, age, sexual orientation
or gender identity. We are committed to creating family-friendly
working conditions. We actively encourage applications by
women. Women with equivalent qualifications and academic achievements
will be preferentially considered unless these are outweighed by
reasons which necessitate the selection of another candidate.
Applications, including a cover letter, CV, list of publications,
research plan relating to the research of Mathematics Münster, and
teaching portfolio, should be submitted electronically, as a single
PDF file, by 30.09.2025 to mathdek@uni-muenster.de.

Subject: Tenure Track Ass. Prof. Position, math. Imaging, Univ. Augsburg, Germany
For a tenure track (pay scale W2, W3 when tenured) professorship at
the University of Augsburg, we seek an internationally visible expert
in the field of mathematical imaging (e.g. image processing, image
reconstruction or related areas). Their (m/f/d) research has
applications in medicine or the natural sciences.
The future holder of the professorship represents mathematical imaging
in research and teaching at the Institute of Mathematics. Experience
in the acquisition of third-party funds and in interdisciplinary
research cooperation is expected. The professorship is part of the
university’s research cluster Centre for Advanced Analytics and
Predictive Sciences (CAAPS). The future holder of the position is
expected to be strongly involved in collaborations with other members
of the centre. The teaching responsibilities include courses for the
joint study programmes of Mathematics and Computer Science, study
programmes in Mathematics, as well as service for other disciplines.
