Subject: Call for Site Bids, 2026 SIAM Conference on Optimization


Call for site preliminary bids: 2026 SIAM Conference on Optimization

The board of the SIAM Activity Group on Optimization is calling for
pre-proposals to host and jointly organize with SIAM the 2026 SIAM
Conference on Optimization (SIOPT 2026). This solicitation is open to
optimization research groups in any continent. Given the previous
locations, applications from outside North America are particularly
encouraged. The SIOPT conference is held every three years and is the
flagship event of our SIAG on Optimization. The conference is usually
held in the last weeks of May. SIOPT 2023 has counted with more than
1000 participants. SIAM will support the conference, including use of
SIAM's abstract submission system, provision of the official
conference website siam.org, and production of the conference
program. SIAM will either have sole financial control (including risk)
of the conference or be in partnership with a local institution.
Preliminary bids should be brief and contain information pertaining to
the location, facilities, logistics (accommodation and
transportation), likely local organizers, and factors that impact
registration fees such as the availability of discounted meeting space
or potential local sponsors. Preliminary bids will be examined by the
SIAG/OPT and SIAM Officers, which will then decide the next steps to
be taken. A final decision will be made by the end of 2023. The
selected bid will be asked to fill out the proposal form available
under "SIAM Activity Group Conference" on the following page:
https://www.siam.org/conferences/about-siam-conferences/propose-a-conference

The deadline to apply is August 15, 2023. Please send your preliminary
bid to SIAG/OPT Program Director, Gabriele Eichfelder
(gabriele.eichfelder@tu-ilmenau.de).

Subject: New Book, A First Course in Options Pricing Theory


A First Course in Options Pricing Theory
by Simone Calogero

Among the many branches of applied mathematics, options pricing theory
occupies a unique position: it utilizes a wide range of advanced
mathematical concepts, making it appealing to mathematicians, and it
is regularly applied at financial institutions, making it
indispensable to practitioners. The emergence of artificial
intelligence in the financial industry has led to further interest in
mathematical finance and has increased the demand for literature on
this subject that is accessible to a large audience. This book
presents a self-contained introduction to options pricing theory and
includes a complete discussion of the required concepts in finance and
probability theory; an introduction to basic models, emphasizing both
critical thinking and practical applications; and over 200 exercises,
several Python codes for the analysis and application of the options
pricing models, and numerical projects intended to help close the gap
between theory and practice. A First Course in Options Pricing Theory
is suitable for an advanced undergraduate course on financial
mathematics and options pricing theory in engineering, computer
science, and applied mathematics programs. The reader is assumed to be
familiar with the standard material in calculus and linear
algebra. Stochastic calculus is not used in the book.

Subject: New Book, Matrix Analysis and Applied Linear Algebra, 2nd Edition


Matrix Analysis and Applied Linear Algebra, Second Edition
by Carl D. Meyer

This second edition has been almost completely rewritten to create a
textbook designed so instructors can determine the degree of rigor and
flexible enough for a one- or two-semester course. The author achieves
this by increasing the level of sophistication as the text proceeds
from traditional first principles in the early chapters to theory and
applications in the later ones, and by ensuring that material at any
point is not dependent on subsequent developments. While theorems and
proofs are highlighted, the emphasis is on applications. The author
provides carefully constructed exercises ranging from easy to
moderately challenging to difficult, many of which condition students
for topics that follow. An accompanying book, Matrix Analysis and
Applied Linear Algebra, Second Edition, Study and Solutions Guide,
contains complete solutions and discussions of each exercise; and
historical remarks that focus on the personalities of the individuals
who created and contributed to the subject's development. Note: these
two titles can be purchased separately, or together as a discounted
bundle.

Subject: New Book, Network Information Systems


Network Information Systems: A Dynamical Systems Approach
by Wassim M. Haddad, Qing Hui, and Junsoo Lee

This text presents a unique treatment of network control
systems. Drawing from fundamental principles of dynamical systems
theory and dynamical thermodynamics, the authors develop a
continuous-time, discrete-time, and hybrid dynamical system and
control framework for linear and nonlinear large-scale network
systems. The proposed framework extends the concepts of energy,
entropy, and temperature to undirected and directed information
networks. Continuous-time, discrete-time, and hybrid thermodynamic
principles are used to design distributed control protocol algorithms
for static and dynamic networked systems in the face of system
uncertainty, exogenous disturbances, imperfect system network
communication, and time delays. Network Information Systems: A
Dynamical Systems Approach is written for applied mathematicians,
dynamical systems theorists, control theorists, and
engineers. Researchers and graduate students in a variety of fields
who seek a fundamental understanding of the rich behavior of
controlled large-scale network systems will also find this book
useful. This book can be used for a first course on control design of
large-scale network systems, such as control protocols for network
systems, network information systems, a dynamical systems approach to
network systems, and network thermodynamic systems. The prerequisites
are a first course in nonlinear systems theory and a first course in
advanced (multivariable) calculus.

Subject: New Book, Rounding Errors in Algebraic Processes


Rounding Errors in Algebraic Processes
by James Hardy Wilkinson

"[This book] combines a rigorous mathematical analysis with a
practicality that stems from an obvious first-hand contact with the
actual numerical computation. The well-chosen examples alone show
vividly both the importance of the study of rounding errors and the
perils of its neglect." A. A. Grau, SIAM Review (1966). Rounding
Errors in Algebraic Processes was the first book to give systematic
analyses of the effects of rounding errors on a variety of key
computations involving polynomials and matrices. A detailed analysis
is given of the rounding errors made in the elementary arithmetic
operations and inner products, for both floating-point arithmetic and
fixed-point arithmetic. The results are then applied in the error
analyses of a variety of computations involving polynomials as well as
the solution of linear systems, matrix inversion, and eigenvalue
computations. The conditioning of these problems is investigated.
The aim was to provide a unified method of treatment, and emphasis is
placed on the underlying concepts.

Subject: PhD Position, Reinforcement Learning, Manchester Metropolitan, UK


The Centre for Advanced Computational Science in the Department of
Computer Science and Mathematics at Manchester Metropolitan University
is inviting applications for a funded 3-year PhD studentship.

The project involves the use of reinforcement learning, optimal
control and computer vision techniques to understand the causal link
between genotype and phenotype in Hypertrophic
Cardiomyopathy. Hypertrophic Cardiomyopathies (HCM) are a group of
familial heart diseases and occur in about one in every 500
births. They are the most common cause of sudden cardiac death in
young athletes and adolescents. The mutations that cause HCM cause the
walls of the heart to thicken and stiffen making it harder for the
heart to pump blood out of the heart and around the body. The
consequences range from fainting, irregular heart rhythms, blood flow
obstruction and sudden death.

The overarching goal is to use a unique combination of reinforcement
learning, optimal control and computer vision techniques, and
algorithms to develop intelligent models to reproduce experimentally
observed HCM behaviour at the subcellular, cellular and tissue
levels. This will be used (1) to understand the causative link between
genotype and phenotype in HCM and other fundamental underlying
mechanisms, and (2) to identify possible therapeutic pathways to
improve patient conditions and quality of life.

Subject: CFP, Special Issue, Symmetry in Probability Theory and Statistics


In this Special Issue of Symmetry, we are aiming to present research
and articles on the concept of symmetry in probability theory and
statistics.

Symmetry plays an important role in all aspects of natural sciences,
e.g., in econometrics, engineering science, computer science and
biology, etc.

Symmetry is a central notion in probability theory and statistics,
appearing in various forms in distribution theory, modeling,
nonparametric estimation, parametric estimation, statistical tests,
change point detection, model averaging, fiducial inference, variable
selection, as well as in many other branches of modern interest. The
objective of this Special Issue is to publish highly motivated,
original, and innovative research articles that apply the notion of
symmetry to current topics in probability theory and statistics.

If you are interested, please contact the Symmetry Editorial Office
(amelia.sun@mdpi.com), or the leading Guest Editor, Prof. Dr. Xinmin
Li (xmli@qdu.edu.cn).
