Ok, let me be completely honest with you guys. I'm reading the book "Conformal differential geometry and its generalizations", of Akivis. In this book the author don't use anything what you are using. He starts with the euclidean case (n dimensions) and then he generalize to the pseudo euclidean...
First of all, thank you so much for answer me. Second, I'm sorry, but I'm not familiar with Lie algebra. I don't know if it is possible to solve this in a more elemental way or maybe you can tell me about a book where I can find this. Again, thanks.
Hi. I'm reading about the compactification of Minkowski Space, and there is a subject that is keeping me awake. They say that the group of conformal transformations is isomorphic to the group of pseudoorthogonal transformations with determinant equal to 1. I don't know how this happen and it...
