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.

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. 2023 /xiii + 288 pages / Softcover / 978-1-61197-763-9 / List $79.00 / SIAM Member $55.30 / OT192 Bookstore link: https://my.siam.org/Store/Product/viewproduct/?ProductId=47420878 ------------------------------------------------------- From: Mitch Graham [log in to unmask] Date: June 01, 2023 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. 2023 /xiv + 991 pages / Hardcover / 978-1-61197-743-1 / List $104.00 / SIAM Member $99.54 / OT188 Bookstore links: Matrix Analysis and Applied Linear Algebra, Second Edition https://my.siam.org/Store/Product/viewproduct/?ProductId=47367687 Study Guide https://my.siam.org/Store/Product/viewproduct/?ProductId=47370651 Bundle https://my.siam.org/Store/Product/viewproduct/?ProductId=47371388 ------------------------------------------------------- From: Mitch Graham [log in to unmask] Date: June 08, 2023 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. 2023 / xiv + 622 pages / Hardcover / 978-1-61197-753-0 / List $114.00 / SIAM Member $79.00 / OT191 Bookstore link: https://my.siam.org/Store/Product/viewproduct/?ProductId=47605805 ------------------------------------------------------- From: Mitch Graham [log in to unmask] Date: June 01, 2023 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. 2023 / xiv + 161 / Softcover / 978-1-61197-752-3 / List $67.00 / SIAM Member $49.60 / CL 89 Bookstore link: https://my.siam.org/Store/Product/viewproduct/?ProductId=47718802 ------------------------------------------------------- From: Niel Van Buggenhout [log in to unmask] Date: May 29, 2023 Subject: Deadline Extended, Numerical Mathematics, Czech Republic, Jul 2023 Prague Workshop on Numerical Mathematics July 20-21, 2023, Charles University, Prague, Czech Republic (hybrid) Deadline for contributed talks has been extended to July 2, 2023.

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. You can find more details and information on how to apply here: https://www.mmu.ac.uk/research/research-study/scholarships#ai-84401-3 The deadline for application is June 15, 2023.

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.
