Varieties of Algebras

Part of the Graduate Texts in Mathematics book series (GTM, volume 88)


This final chapter returns to the general theory of algebras over a field. It provides a brief introduction to the theory of polynomial identities for algebras. Our main goal is to prove Amitsur’s Theorem which establishes the existence of finite dimensional central simple division algebras that are not crossed products. The choice of topics in the chapter is motivated by this objective. Fortunately, many interesting results on polynomial identities are encountered in the proof of Amitsur’s Theorem: the Amitsur—Levitzki Theorem, the existence of central polynomials, and the Kaplansky—Amitsur Theorem on primitive PI-algebras.
