An introduction to semi-Riemannian geometry as a foundation for general relativity Semi-Riemannian Geometry: The Mathematical Language of General Relativity is an accessible exposition of the mathematics underlying general relativity. The book begins with background on linear and multilinear algebra, general topology, and real analysis. This is followed by material on the classical theory of curves and surfaces, expanded to include both the Lorentz...

The Art of Spiral Drawing offers a fresh, modern take on everyone's favorite childhood toy from the 1960s through today, the Spirograph (R). With The Art of Spiral Drawing, no complicated tools are needed, as artists of all skill levels learn to create their own spiral art using little more than paper and a pen or pencil. Written and illustrated by Jonathan Stephen Harris, the author of the popular The Art of Drawing Optical Illusions, the book opens...

Uses the concept of graph rigidity as the basis for describing the multi-agent formation geometry and solving formation control problems. Considers different agent models and formation control problems. Control designs throughout the book progressively build upon each other. Provides a primer on rigid graph theory. Combines theory, computer simulations, and experimental results Market description: Primary: Researchers and practitioners working in...
