Which geometries on a smooth manifold (apart from Lorentzian metrics) can serve as a spacetime structure? This question is comprehensively addressed from first principles in eight lectures, exploring the kinematics and gravitational dynamics of all tensorial geometries on a smooth manifold that can carry predictive matter equations, are time-orientable, and allow to distinguish positive from negative particle energies.

A regular, smooth, and logically consistent introduction to the subject starting with basic facts like Coulomb law and ending with Einstein's theory of gravitation. A book for mathematics students, references to physical intuition are minimized.
by Clement V. Durrell - G. Bell & Sons
Concise and practical, this text sketches the mathematical background essential to understanding the fundamentals of relativity theory. Subjects include the velocity of light, measurement of time and distance, and properties of mass and momentum.
by Hendrik Antoon Lorentz - Feedbooks
There is a constant demand for information about this much-debated topic of relativity. In order to make a popular explanation of this far-reaching theory available, the present book is published. (first published in 1920)
by John D. Norton - Nullarbor Press
Aimed at people who do not know enough physics to understand what Einstein did and why it was so important. The course presents just enough of Einstein's physics to give students an independent sense of what he achieved and what he did not achieve.
