PI-Algebras: An Introduction (Lecture Notes in Mathematics) by Nathan Jacobson (Repost)

These are lecture notes for a course on ring theory given by the author at Yale, September - December, 1973. The lectures had two main goals: first, to present an improved version of the theory of algebras with polynomial identity (over a commutative coefficient ring) based on recent results by Formanek and Rowen and second, to present a detailed and complete account of Amitsur's construction of non-crossed product division algebras.
