Subject: Fred Krogh, Unfinished Work to Share

I have some unfinished business I would like to share. I have some
work that I think may be of interest to others. I have been dealing
with metastatic bone cancer for about 6 years, and the end could occur
at anytime.

You can find details at

Rather than go quietly into the night, I plan to keep working. What
is posted is posted now as future days cannot be counted on. Even
good days have me greatly fatigued.

Life has been good, and algorithms in the area of computational
mathematics have been a source of joy for me.

My Best wishes to all of you,
Fred Krogh

Subject: Possible very short proof of Fermat's Last Theorem

So far, two mathematicians have found no error in my one-page possible
proof of Fermat's Last Theorem. If the proof is valid, it will be of
major interest, since the shortest existing proof of the Theorem is
well over 100 pages of some of the most sophisticated mathematics.
The possible proof is on page 33 of Part 1 of "Is There a 'Simple'
Proof of Fermat's Last Theorem?" on

I will welcome comments. -- Peter Schorer,

Subject: Version 13 of INTLAB, MATLAB/Octave toolbox for Reliable Computing

The next Version 13 of INTLAB, the MATLAB®/Octave toolbox for reliable
computing, is available.

INTLAB is entirely written in MATLAB®/Octave and comprises of some
2000 m-files with 70KLOC w/o comments, 127KLOC with comments.

Changes to the previous Version 12 of INTLAB are:
- A new toolbox "flbeta" for the simulation of precision-p base-beta
arithmetic following IEEE754, covering directed roundings, subnormal
numbers, scalars, vectors, matrices and flbeta intervals for a
specifiable exponent range. A base between 2 and 64 can be defined
with precision depending on the base.
- A new toolbox "dd" for a double-double arithmetic.
- A new toolbox "cpair" for an alternative and fast double-double
- A new method for ODEs to reduce the truncation error in Taylor model
- Redefinition of the relative error, relative accuracy and distance
of intervals.
- More than one third of all 2000 m-files were changed/improved.

Otherwise, INTLAB toolboxes cover
- interval arithmetic for scalars, vectors and matrices, real and
- affine arithmetic
- algorithmic differentiation by gradient, hessian and taylor
- slopes, polynom and long toolboxes
- ODEs by Taylor models and AWA
and others. Many problem solving routines are included for linear and
nonlinear systems, local and global optimization and much more. The
ODE toolbox was designed and written by Florian Bünger.

INTLAB is available at

Subject: Postdoc Position, Integer Linear Optimization, Brazil

One post-doctoral position is available to work within the scope of
the Center for Research in Mathematical Sciences Applied to Industry
(CeMEAI), one of the Research, Innovation and Dissemination Centers
(RIDCs) supported by the São Paulo Research Foundation (FAPESP).
CeMEAI is hosted by the University of São Paulo's Institute of
Mathematical and Computer Sciences (ICMC-USP) in São Carlos, Brazil,
and headed by Prof José Alberto Cuminato. The fellow will develop
integer optimization models and solution methods for production
planning problems in the food industry and logistical problems in the
sugarcane industry. As he/she will have to deal with the integrated
lot scheduling and distribution problem with the perishable items,
there is a need to synchronize scarce resources among multiple
production lines, therefore he/she must consider scheduling harvest
fronts, determining their harvesting areas based on available
capacities and transportation. Novel mathematical models will be
developed or extended to deal with these problems and solution methods
based on problem decomposition. However, exploring optimization
methods hybridized with machine learning techniques is crucial to
achieving good solutions to the problems under study.

Profile: Exceptional scientific performance, knowledge of operational
research and high level of autonomy. Candidates must demonstrate
programming and optimization software skills. Candidates must have got
their PhD in the last 7 years. Preferred profile: Published papers in
the area of research (mathematical modeling and development of
heuristics). Application: Please send your application before March
20, 2024 to Prof. Maristela Oliveira dos Santos (,
who will be supervisor for this project. Please indicate
“post-doctoral application – Operations Research” in the
subject. Applications should include CV (pdf), statement of research
interests, and two contacts for recommendation letters (pdf).

to polyhedral meshes and accounting for a linear elastic rock
behavior with small deformations and frictional contact at
matrix-fault interfaces,
- to couple this new contact-mechanical module with the multiphase
non- isothermal flow model already implemented in ComPASS based on a
robust iterative coupling strategy.

mathematics and be familiar with scientific programming (C++, Python,
MPI) and collaborative development tools.

supervised by Jemima Tabeart and the student will join the active
Centre for Analysis, Scientific Computing and Applications. Candidates
with a strong applied Mathematics background and a Master’s degree in
a numerate subject are encouraged to apply.

The PhD project will develop numerical linear algebra methods for data
assimilation problems motivated by applications to numerical weather
prediction and geosciences. Possible research directions include
developing new preconditioners, iterative solvers and designing
practical implementations under challenging operational
constraints. Candidates do not require prior knowledge of data
assimilation, but should be excited to apply numerical analysis
techniques to high-dimensional problems of real-world importance.

Applications will be considered as soon as they are received. The
procedure may be closed earlier than the final application date (April
6, 2024). Some flexibility in the starting date of the position is
possible, with an ideal starting date before October 2024. Full
information can be found at

Subject: PhD Position, Scientific ML, Inria Sophia Antipolis, France

Full Announcement:

Applications are welcome at the Inria center of the University Cote
d’Azur on the French Riviera situated in the vibrant technopole of
Sophia- Antipolis, for a Master internship (4 to 6 months duration)
followed by a three year fully funded PhD positon (to start
immediately after or at commonly agreed date), in the context of a
multi-partner collaborative project with the Inria from University of
Lorraine (Nancy) and TU Eindhoven (The Netherlands). The aim of the
project is to study multilevel distributed strategies for fast
training of physics-based neural networks for modelling
electromagnetic wave propagation in frequency regime. We will in
particular investigate strategies that can accurately and efficiently
deal with the simulation of electromagnetic wave interaction with
heterogeneous media, and geometrically complex scattering structures.

The internship position is open to students currently enrolled in an
MSc in Applied mathematics or Scientific computing or connecting
disciplines but with a strong mathematical background. The candidate
is expected to have a solid knowledge in numerical methods for the
solution of PDEs, basic programming skills and a minimal knowledge of
Machine Learning.

The application must be done online via the officia Inria webpage
above. The application package needs to contain a CV, a letter of
motivation, copies of relevant course transcripts along with the
contacts of at least two academic referees.
