Differential Manifold is the framework of particle physics and astrophysics nowadays.
It is important for all research physicists to be well accustomed to it and even experimental physicists should be able to manipulate equations and expressions in that framework.This book gives a comprehensive description of the basics of differential manifold with a full proof of any element.
A large part of the book is devoted to the basic mathematical concepts in which all necessary for the development of the differential manifold is expounded and fully proved.This book is self-consistent: it starts from first principles.
The mathematical framework is the set theory with its axioms and its formal logic.
No special knowledge is needed.
