Subject: TDS-CONTROL, MATLAB Release

TDS-CONTROL is an integrated MATLAB package for the analysis and
control of linear time-delay systems. The package can deal with delay
systems of retarded and neutral type. These systems are assumed in
state-space form, although functionality is provided to convert a
transfer matrix representation. Firstly, the package offers various
methods to analyze LTI time-delay systems. More specifically, it
contains methods for computing the spectral abscissa, the H-infinity
norm, the pseudospectral abscissa, and the distance to instability. As
TDS-CONTROL is designed with neutral equations in mind, it has the
appealing feature that the sensitivity of certain quantities (such as
the spectral abscissa and H-infinity norm) with respect to
infinitesimal delay perturbations is explicitly taken into
account. Secondly, TDS-CONTROL contains functionality to design
fixed-order dynamic output feedback controllers for which the order of
the controller may be smaller than that of the plant. These
controller-design algorithms are based on optimizing the spectral
abscissa, the H-infinity norm or a combination of both. For example,
to design a (strongly) stabilizing controller the (strong) spectral
abscissa is minimized. Furthermore, structure can be imposed on the
controller, which enables the design of decentralized and PID
controllers. Finally, by allowing the plant to be described in delay
descriptor form (i.e. by delay differential-algebraic equations),
Pyragas-type, acceleration and delay-based feedback controllers can be

TDS-CONTROL has been written by P. Appeltans, under the supervision of
H. Silm and W. Michiels. The software is available from

The manual has been conceived to provide also a tutorial on spectral
properties and control of time-delay systems, by means of 32 examples:

Subject: New Book, Algorithms for Sparse Linear Systems, Open Access

We are pleased to announce the publication of our new open access book

Algorithms for Sparse Linear Systems
by Jennifer Scott and Miroslav Tuma

Necas Center Series, Birkhauser Cham, April 2023
Softcover ISBN: 978-3-031-25819-0
eBook ISBN: 978-3-031-25820-6
Number of pages: XIX, 242

Large sparse linear systems of equations are ubiquitous in science,
engineering and beyond. This open access monograph focuses on
factorization algorithms for solving such systems. It presents
classical techniques for complete factorizations that are used in
sparse direct methods and discusses the computation of approximate
direct and inverse factorizations that are key to constructing
general-purpose algebraic preconditioners for iterative solvers. A
unified framework is used that emphasizes the underlying sparsity
structures and highlights the importance of understanding sparse
direct methods when developing algebraic preconditioners. Theoretical
results are complemented by sparse matrix algorithm outlines.

The book is aimed at students of applied mathematics and scientific
computing, as well as computational scientists and software developers
who are interested in understanding the theory and algorithms needed
to tackle sparse systems. It is assumed that the reader has completed
a basic course in linear algebra and numerical mathematics.

Subject: Postdoc Position, Sapienza Univ of Rome, Italy

The Department of Basic and Applied Sciences for Engineering at
Sapienza University of Rome is looking for a post-doctoral researcher
in numerical analysis. The project will focus on boundary integral
methods for Stokes flow.

In recent years, the boundary integral method (BIM) has proved itself
to be a valuable tool for the solution of many physical and
engineering problems. One of the main advantage of this approach is
that the equations are defined only at the boundary, which then plays
a key role. We are interested in those problems with large surface to
volume ratio, where the dynamic at the interface is very important and
it is then natural to consider integral equations. The project will
focus on how electric fields can affect the dynamics of drops: this
effect is studied with the Leaky Dielectric model, that we solve using
a BIM, that is also used to solve the Stokes equations. Special
attention will be spent for dealing with non-smooth surfaces.

We are please to announce that we are seeking strong postdoctoral
candidates for the project Krylov subspace methods for non-symmetric
PDE problems: a deeper understanding and faster convergence. The
positions will start as soon as possible after July 1, 2023. The
project concerns the solution of linear systems arising from the
numerical discretisation of partial differential equations (PDEs),
which are critical to simulations in a swathe of applications. The
methods of choice for these systems are often preconditioned Krylov
subspace methods, but for nonsymmetric problems theory for
preconditioners and solvers is still lacking. The overarching aim of
this research is to develop novel theory that underpins preconditioner
design and efficient solvers for systems with nonsymmetric coefficient
matrices. The investigators are Jennifer Pestana at the University of
Strathclyde (Glasgow) and Kirk M. Soodhalter at Trinity College,
Dublin. The project is funded by the UK Engineering and Physical
Sciences Research Council and Science Foundation Ireland.

The postdoctoral researchers will have opportunities to work with a
range of international experts on fundamental problems in numerical
linear algebra, and will apply novel methods to applications in wave
problems and wind farms. The funding will support postdoctoral
research associates' travel to select conferences and visits to
related researchers so that the postdoctoral associates can benefit

Subject: PhD Position, Numerical Methods/Quantum Systems, Germany

We are seeking a highly motivated PhD student to work on theoretical
aspects related to the mathematics and physics of open quantum
many-body systems. The research will focus in particular on the
development of numerical methods based on tree-tensor networks; the
simulation of open many-body quantum systems with long-range
interaction; and the characterisation of quantum phases and phase
transitions. This PhD position will be embedded in the Research Unit
FOR 5413 "Long-range interacting quantum spin systems out of
equilibrium: Experiment, Theory and Mathematics" which is funded by
the German Research Foundation (DFG). The Research Unit addresses
questions concerning many-body quantum systems with long-range
interactions. Its ultimate goals are the understanding, realisation
and control of complex quantum matter possessing collectively enhanced
yet robust properties with applications in emerging quantum
technologies, such as metrology and sensing. It builds on the Center
for Quantum Science at the University of Tubingen and seeks to
establish a flourishing research environment that brings together an
interdisciplinary group of scientists from experimental and
theoretical physics as well as mathematics. The PhD will be supervised
by Prof. Dr. Christian Lubich (Department of Mathematics) and
co-supervised by Prof. Dr. Igor Lesanovsky (Institute for Theoretical
Physics). Candidates need to have a strong background in mathematics
and physics, a strong academic record and commitment. They need to be
committed to engage with all the members of the Research Unit FOR 5413
and to support and participate in the activities of the research
group. Applications should include a cover letter (including
motivation for applying to this position), a CV (including publication
list), a copy of the applicant's master thesis and transcripts (all
collated in a single pdf file). Applicants should also arrange for at
least one recommendation letter. All documents shall be sent to and

The offered position will run for at least 3 years. Review of the
applications will begin on June 30th 2023. The position should start
on October 1st 2023.
