An Alternative Approach to Lie Groups and Geometric Structures

In this very nice and unusual book, the author proposes an alternative approach to the theory of Lie groups, together with some applications and generalization of it. The approach proposed is inspired by the geometric theory of partial differential equations (PDEs) and Lie pseudogroups. In this respect, it is much closer in spirit to the original works of Lie and Klein than the current modern theory...The book is suitable for students at a master's level.
