Across production, transportation, logistics, and energy, a central challenge is modeling and optimizing collective actions. This book aims to bridge game theory and systems and control by developing tools for incentive-based control in dynamic, uncertain, and networked multiagent systems; it extends both cooperative and noncooperative game models into a control-oriented framework, emphasizing feedback, learning, and decision making under uncertainty. Incentive-Based Control via Game Theory stands apart from existing literature by offering a design-oriented approach that focuses on using game theory to design mechanisms and control strategies that guide self-interested agents toward stable and socially desirable outcomes in dynamic, uncertain systems. It also includes novel engineering-focused content that introduces advanced topics rarely covered in game theory and engineering texts, including dynamic coalitional games, reverse Stackelberg games, and rigorously analyzed best- response dynamics. Additionally, it provides an application-driven perspective that combines mathematical rigor with real-world engineering applications, showing how theory translates into practical implementation. 2026 / xxiv + 283 pages / Softcover / 978-1-61197-891-9 / List $89.00 / SIAM Member $62.30 / DC45 Bookstore link: https://epubs.siam.org/doi/10.1137/1.9781611978926 ------------------------------------------------------- From: Birgit Jacob bjacob@uni-wuppertal.de Date: April 29, 2026 Subject: Next pH Seminar, 6 May Dear all, We are excited to invite you to the next pH Seminar!

Castillo jcastillo@sdsu.edu Date: April 30, 2026 Subject: Mimetic Operators Library Enhanced (MOLE) Tutorial, 12 May The Computation Science Research Center (CSRC) at San Diego State University invites you to: A Tutorial on The Mimetic Operators Library Enhanced (MOLE) May 12, 2026 from 10 AM to 12:00 PM. PDT. MOLE is a high-quality numerical library that implements high-order mimetic difference operators to solve PDEs in C++ and MATLAB/Octave. It provides discrete analogs of the most common vector calculus operators: Gradient, Divergence, Laplacian, and Curl. These operators (highly sparse matrices) act on staggered grids (uniform, non-uniform, curvilinear) and preserve locally and globally quantities of interests for systems of conservation laws. This tutorial will cover an introduction to MOLE mimetic difference operators; gradient, divergence, laplacian and curl for C++ and Octave/MATLAB users. Attendants will learn how to use the MOLE library through examples, and also review the installation and guidelines to contribute to the MOLE library. Please, read the Getting Started Section in mole-docs.readthedocs.io/ and install or clone the MOLE library. Installation support will be provided 90-minutes prior to the beginning of the tutorial. The tutorial is free and will be held in person at SDSU's Bioscience Center Auditorium on May 12, 2026 from 10 AM to 12:00 PM U.S. PT, and also online. To register for the tutorial in person or online, please fill out this form: https://forms.gle/7KZ8t3zCUxu7f6vB7.
