Description

This volume presents contributions of modern developments in analysis, PDEs and geometric analysis by leading experts, as well as distinguished junior and senior researchers.

The book includes contributions from speakers at the Methusalem Colloquium, Methusalem Junior Seminar, and Geometric Analysis Seminar, all of which were held at the Department of Mathematics, Ghent University from 2023 to 2024. Additionally, it features colloquia and mini-courses delivered by visiting and invited guests.

The book has two main directions:

Analysis and PDEs: Covers topics in noncommutative analysis and geometry, functional and harmonic analysis, geometry and spectral methods, and applications to mathematical physics. Geometric Analysis: Covers topics in modern analytic techniques applied to elliptic, hypoelliptic, and subelliptic PDEs. A central theme of this book is the role of pseudo-differential operators in spectral analysis of geometric structures, with direct implications for index theory, noncommutative geometry, and quantization.

Geometry of Ellipses and Planetary Orbits

Format: Paperback / softback, 225 pages, height x width: 235x155 mm, XIII, 225 p.
Pub. Date: 01-Jul-2026
ISBN-13: 9783032262714

Description

This open access book is intended to give a bird's-eye view of ellipses and planetary orbits. The only background required is secondary-school Euclidean geometry, analytic geometry, and trigonometry. That doesn't mean that the theorems and proofs are easy; to the contrary, many are very challenging.

Although Isaac Newton invented the calculus and used it to study motion, from the time of the Greeks, proof meant proof by geometry. The book contains Newton's detailed geometric proof of the inverse-square law of orbits, based on Conic Sections Treated Geometrically, a widely used textbook from the nineteenth century written by William H. Besant. An important feature of the book is the numerous diagrams that are much more detailed than those appearing in the textbooks from the nineteenth century.

Turning to planetary orbits, the book presents Kepler's equation for computing the position, speed and direction of a planet in its orbit, followed by the computation of Lagrange points, which are points in the solar system where a spacecraft can be placed so that the period of its orbit is the same as the Earth's.

The history of mathematics has (or should have) an important place in mathematics education. Euclid is well-known but mathematicians were equally familiar with Conics by Apollonius of Perga. Some of his results are given in modern notation, although the presentation is faithful to his style. In addition, Kepler's own geometric proof of his First Law is given.

The final chapter presents challenging theorems on ellipses: the Steiner inellipse, Marden's Theorem, the theorems of Pascal and Brianchon, and Newton's Ellipse Theorem.

Elements of Functional Analysis:
From Banach Spaces to Elliptic Problems

Format: Paperback / softback, 442 pages, height x width: 235x155 mm, 1 Illustrations, black and white
Series: Universitext
Pub. Date: 02-Aug-2026
ISBN-13: 9783032292094

Description

Functional analysis can be understood as a shift, within mathematical analysis, from the study of individual functions to the study of function spaces, their structures, and the mappings between them. Developed primarily during the 20th century, this theory continues to be essential for the study of partial differential equations.

This textbook begins with the general theory: Banach spaces, Hilbert spaces, and the spectral theory of operators. It then proceeds to a thorough account of Schwartzs Theory of Distributions and some of its applications, such as the fundamental solutions of classical operators in physics, the MalgrangeEhrenpreis Theorem, hypoelliptic operators, and the Schrödinger equation. An extensive chapter is dedicated to the study of Sobolev spaces, including functions of bounded variation. These spaces provide the appropriate framework for the study of elliptic boundary value problems, which form the focus of the final chapter.

Drawing on years of teaching experience, this textbook is ideal for introductory graduate courses, featuring historical notes and numerous exercises that reinforce learning and complement the core material.

Description

Mikio Sato (19282023) is one of the most original and influential mathematicians of the twentieth century, whose ideas continue to shape modern mathematics. He initiates the theories of hyperfunctions and D-modules, laying the foundations of what he later called algebraic analysis. These innovations establish a unifying framework for analysis, algebra, and geometry, while revealing deep connections with theoretical physics. His work profoundly influences developments in analysis, number theory, holonomic quantum field theory, and integrable systems.

This three-volume collected edition presents a representative and authoritative selection of Satos writings, reflecting both the breadth of his vision and the coherence of his thought. Volume I focuses on algebraic analysis, especially hyperfunction theory and microlocal analysis. Volume II centers on mathematical physics, notably holonomic quantum field theory. Volume III gathers works on prehomogeneous vector spaces, number theory, exact WKB analysis, and integrable systems, including soliton equations, highlighting the unity of Satos mathematics across diverse domains.

Each volume opens with substantial scholarly commentaries by leading experts. These commentaries place Satos work in historical and intellectual context, clarify the state of the subject before his contributions, and elucidate his conceptual innovations. Together, they comprise over one hundred pages of critical assessment and reflection, offering insight into the enduring impact of Satos ideas on later developments.

To document the full scope of his research and influence, the edition includes a comprehensive bibliography encompassing informal materials not reproduced in these volumes.

This collection stands as both a definitive record of Satos achievements and an enduring source of inspiration, demonstrating how bold conceptual thinking can open new directions in mathematics and providing a model for future generations.

Description

This monograph explores feedback stabilization of bilinear control systems evolving in Hilbert and Banach spaces, with particular emphasis on unbounded control operators arising in PDE models. It develops a unified and comprehensive framework for weak, strong, robust, and exponential stabilization, incorporating nonlinear feedback laws, such as homogeneous, normalized, and switching feedbacks. By combining tools from functional analysis, semigroup theory, and control theory, this book bridges linear and nonlinear stabilization strategies and highlights the robustness of feedback mechanisms in infinite-dimensional systems. Feedback Stabilization of Bilinear Systems will serve as an ideal resource for researchers, graduate students, and practitioners who seek deeper insight into the stabilization of PDEgoverned systems as well as applications where bilinear dynamics naturally arise.

Characteristic Operator Function and Related Topics:
A Tribute To Moshe Livsic

Format: Hardback, 504 pages, height x width: 235x155 mm, XIII, 504 p.
Series: Operator Theory: Advances and Applications
Pub. Date: 01-Aug-2026
ISBN-13: 9783032286970

Description

This volume contains translations of six of the original papers of Moshe Livsic on the characteristic operator function, together with a collection of contributions devoted to MosheLivsics theory of the characteristic operator function and its impact on the spectral analysis of nonselfadjoint operators, a theory first introduced in the 1940s. This theory provides a framework for the spectral analysis of non-selfadjoint and non-unitary operators and has since become a cornerstone of modern operator theory. Over the past seventyfive years, Livsics theory has exerted a lasting influence on analysis, complex analysis, linear systems theory, and a broad range of related topics. The volume examines how Livsics theory has shaped the study of pairs of commuting operators, a research direction initiated in the early 1970s with the aim of linking systems theory, nonselfadjoint operator theory, and Riemannian geometry.

The contributions collected here reflect the scope and depth of Livsics work at the intersection of operator theory, geometry, and systems theory. This book will be a valuable resource for researchers and advanced graduate students working in operator theory, analysis, systems theory and related areas.

A number of recollections from colleagues, students and friends of Moshe Livsic are also included.

Description

This book gathers written notes from three lecture series presented at the PIMSIFDSNSF Summer School on Optimal Transport, held at the University of Washington in June 2022. The summer school was the first major event organized by the Kantorovich Initiative, a nascent research consortium linking several universities in the Pacific Northwest and dedicated to advancing the mathematics of MongeKantorovich transport problems and their many applications. The mini-courses offered during the summer schooland the lecture notes collected hereare poised to have a substantial impact on the next generation of optimal transport researchers. The range of topics included in this volume reflects the remarkable breadth of contemporary research in the field. Felix Otto and Lukas Kochs contribution, based on Ottos mini-course, presents a variational perspective on the regularity theory of optimal transport. Alfred Galichon and Antoine Jacquets notes, drawn from Galichons mini-course, explore the links between optimal transport and matching models in economics. Finally, Geoffrey Schiebingers notes survey his mini-course on applications of optimal transport in developmental biology.
