""An Introduction to Tensor Calculus and Relativity"" by Derek Frank Lawden is a comprehensive guide to the mathematical concepts of tensor calculus and their applications in the field of relativity. The book begins with an introduction to the basics of tensor calculus, including tensor algebra, tensor calculus, and tensor analysis. It then moves on to cover the principles of special and general relativity, including the Lorentz transformation, the metric tensor, and the curvature tensor. The book also covers the mathematical tools necessary for understanding relativity, including differential geometry, Riemannian geometry, and the calculus of variations. Throughout the book, the author provides numerous examples and exercises to help readers develop their understanding of the material. This book is an ideal resource for students and researchers in physics, mathematics, and engineering who are interested in learning about tensor calculus and its applications in relativity.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
