This volume is a collection of contributed papers that explore the solution of mathematical programming problems where the standard assumption of differentiability—the ability to calculate smooth derivatives—is dropped. Nondifferentiable optimization (also known as nonsmooth optimization) addresses problems involving functions with sharp "corners" or discontinuous derivatives, which cause c…
This textbook provides a rigorous introduction to functional analysis with a specific focus on Hilbert spaces and their practical applications. Balakrishnan views functional analysis as the essential language for addressing complex problems in system optimization, control systems, and mathematical economics. The text covers foundational topics such as linear operators, spectral theory, and semi…
Often referred to simply as "Zygmund," this is the definitive, foundational treatise on Fourier analysis. Volume I covers the core theory of trigonometric series, including convergence and summability, the properties of Fourier coefficients, and the theory of Hardy spaces . Zygmund’s work transformed the field from a collection of isolated results into a unified branch of mathematical analysi…
This textbook provides a foundational introduction to three-dimensional analytical geometry, designed specifically for undergraduate students (B.A./B.Sc.). It covers essential topics such as the coordinates of points in space, equations of lines and planes, and the properties of curved surfaces including spheres, cones, and cylinders. The book is characterized by its structured approach to solv…
Trace Analysis: Spectroscopic Methods for Molecules (1986), edited by Gary D. Christian and James B. Callis, serves as a comprehensive technical guide to the identification and quantification of molecular species at extremely low concentrations. As Volume 84 of the Chemical Analysis series, it was designed as a direct companion to Volume 46, which covered trace analysis for elements. While ele…
This classic work introduces readers to a completely different way of looking at familiar geometric facts by focusing on transformations of the plane that do not alter the shape or size of figures. It specifically explores distance-preserving transformations—such as translations, rotations, reflections, and glide reflections—to bridge high school Euclidean geometry with sophisticated group-…
This textbook offers a rigorous introduction to projective geometry, a field that studies properties invariant under projection. Unlike standard Euclidean geometry, which focuses on distance and angle measurements, this text explores foundational concepts such as incidence, duality, and cross-ratio using both synthetic and algebraic methods. Wylie meticulously develops the theory from initial a…
One of the first college-level texts for elementary courses in the subject, this book provides a concise, readable introduction to non-Euclidean geometry geared toward students with a background in calculus. It offers a detailed historical treatment of the centuries-long attempt to prove Euclid’s parallel postulate and covers key topics such as hyperbolic and elliptic plane geometry and trigo…
This classic textbook provides a rigorous yet accessible introduction to the fundamental concepts of differential geometry, tailored for advanced undergraduate and graduate students in mathematics and physics. The text is divided into two primary parts: the first employs vector methods to explore the classical theory of curves and surfaces, while the second introduces the more modern language o…
This textbook is essentially compiled from lecture notes delivered by David Vernon Widder at Harvard University. It provides a rigorous and lucid introduction to the mathematical theory of transforms, starting with a rapid overview of Laplace integrals and their use in solving differential equations. Rather than being an encyclopedic reference, the book focuses on fundamental aspects of the the…
