I must warn you. English is not my native language, but I have made my best to provide the text of the chapters in English. Please be merciful with the errors you will find. The aim was to provide the possibility of making accessible the text for those who did not speak/read Spanish.
So, with my apologies in advance, you can click HERE to get the pdf file. Thanks to Damián Gulich who provided us the translation of Chapter 3.
I hope you enjoy it.
