Algebra (2nd Edition) written by Michael Artin , Massachusetts Institute of Technology.
According to Michael Artin:
This book began many years ago in the form of supplementary notes for my algebra classes. I wanted to discuss someconcretetopics such as symmetry, linear groups, and quadratic number fieldsin more detail than the text provided, and to shift the emphasis in group theory from permutation groupsto matrix groups. J...Jattices, another recurring theme, appeared spontaneously.
My hope was that the concrete material would interest the students and that it would make the abstractions more understandable- in short, that they could get farther bylearning both at the same time. This worked pretty welLIt tookmequite a while to decide what to include, but I gradually handed out more notesand eventually began teaching from them without another text. Though this produced a bookthat is different from most others, the problemsI encountered while fitting the parts together caused me many headaches. I can't recommend the method.
