Subject: Mathematics of Lattices and Cybersecurity, USA, Apr 2015

Lattices are abstractly very simple objects, yet their concrete
realizations contain beautifully intricate problems that are
stubbornly difficult even in low dimensions. For example, our present
day understandings of densest lattice packings and reduction theory
are still plagued with large gaps.

In the 1970's and 1980's lattices entered the world of cryptography as
tools used to break certain crypto systems, particularly those based
on the subset sum problem, and since the 1990's they have become
increasingly important in the building of other types of crypto
systems (thanks to the difficulty in the underlying
mathematics). Their significance has recently been bolstered by
average-case complexity bounds and their present resistance to quantum
computing attacks.

Currently the theory of lattices is a lively research topic among
mathematicians, computer scientists, and experts in
cybersecurity. However, to this date, there has been little to no
interaction between these communities. The goal of this workshop is to
stimulate activity between these different groups interested in
lattice problems. Topics to be covered include, but are not restricted
to, recent results on densest lattice packings, the geometry of
lattice moduli space and its connections with automorphic forms and
algebraic number theory, cryptographic applications of lattices, and
the state of the art of lattice reduction in high dimensions.

Subject: 10 Years Shifted Laplacians, Germany, May 2015

The Helmholtz equation appears in a wide range of science and
engineering disciplines in which wave propagation is modeled. Solving
this equation numerically is notoriously difficult. A landmark
contribution in reducing the computational complexity is the
publication of the Complex Shifted Laplace preconditioner by the TU
Delft 10 years ago. In recent work the TU Delft group has developed
an algorithmic extension that further reduces the computational

On Monday, May 18th, the TU Delft Helmholtz organizes a seminar to
celebrate the Complex Shifted Laplace preconditioner, to put its
development in perspective, to showcase recent development and to look
into the future. Three speakers from academia (Prof. Livshits from
Ball State Indiana, Dr. Stolk from UvA Amsterdam and Prof C. Vuik from
TU Delft) and two from industry (Dr. Tournour from Siemens
International and Dr. Plessix from Shell) will share their unique
insights into this field. The workshop should therefore appeal to both

Subject: Computational and Analytical Aspects of Image Reconstruction, USA, Jul 2015

Computational and Analytical Aspects of Image Reconstruction
(July 13-17, 2015)

The mathematical study of image reconstruction problems can have a
huge impact on human life. More efficient mathematical algorithms for
X-ray tomography and more accurate mathematical models in seismic or
hybrid imaging can lead to better imaging devices in fields such as
medicine and remote sensing. Developing the underlying mathematics,
including the analysis of reconstruction stability, regularization,
singularity characterization, and efficient algorithms, may lead to
fewer false positives in fields such as medical, seismic and radar

This topical workshop will bring together international experts
working in computational and analytical aspects of image
reconstruction (including but not limited to electron- microscope
tomography, hybrid imaging, radar and sonar, full waveform inversion
of seismic imaging and X-ray CT) as well as postdoctoral fellows and
graduate students. There will be multiple introductory-level talks
for early-career researchers and non- specialists in the area on both
the mathematics involved and the scientific and industrial
applications. Speakers and participants from industry will be included
to strengthen the practical aspects of the workshop.

ICERM’s IdeaLab for Early Career Researchers:
Inverse Problems and Uncertainty Quantification
July 6-10, 2015

IdeaLab is a one-week summer program aimed at early career researchers
(within 5 years of their Ph.D.) held at Brown University’s Institute
for Computational and Experimental Research in Mathematics
(ICERM). IdeaLab focuses on a topic at the frontier of research.
Participants are exposed to a problem whose solution may require broad
perspectives and multiple areas of expertise. Senior researchers
introduce the topic in tutorials and lead discussions. The
participants break into teams to brainstorm ideas, comprehend the
obstacles, and explore possible avenues towards a solution. The teams
are encouraged to develop a research program proposal. On the last
day, they present their ideas to one another and to a small panel of
representatives from funding agencies for feedback and advice.

Inverse problems arise in an enormous variety of science and
engineering applications. The goal of this IdeaLab is to lay out the
fundamentals of uncertainty quantification for inverse problems in a
relatively rapid but hands-on manner, so that participants can
understand and fluently discuss the current state of the art.

Subject: Numerical Methods for Large-Scale Nonlinear Problems, USA, Aug 2015

Numerical Methods for Large-Scale Nonlinear Problems and Their
Applications (August 31 - September 4, 2015)

Over the last 20 years or so, Newton-Krylov methods have developed to
maturity, allowing effective fully-coupled treatment of a broad range
of large-scale nonlinear problems. This development has set the stage
for addressing more difficult problems with more challenging
features. Additionally, applications for which state-of-the-art
Newton-Krylov approaches are inapplicable have recently exposed
several basic research questions. At the same time, there remain many
problem-specific methods and legacy codes that are still useful and
can be regarded as a resource for further development.

This workshop will include mathematicians and computer scientists who
work on algorithm design, implementation, and analysis, together with
disciplinary scientists and engineers who use the algorithms in
applications and have a working knowledge of their capabilities,
weaknesses, and limitations. The major foci of the workshop will be
acceleration methods, in particular Anderson acceleration; methods for
nonlinear problems that have significant stochastic aspects; methods
for nonsmooth problems; and various techniques for improving
robustness, such as nonlinear preconditioning.
