Polynomial Identities and Asymptotic Methods
Share this pageAntonio Giambruno; Mikhail Zaicev
This book gives a state of the art approach to the study of
polynomial identities satisfied by a given algebra by combining
methods of ring theory, combinatorics, and representation theory of
groups with analysis. The idea of applying analytical methods to the
theory of polynomial identities appeared in the early 1970s and this
approach has become one of the most powerful tools of the theory.
A PI-algebra is any algebra satisfying at least one nontrivial
polynomial identity. This includes the polynomial rings in one or
several variables, the Grassmann algebra, finite-dimensional algebras,
and many other algebras occurring naturally in mathematics. The core
of the book is the proof that the sequence of codimensions of any
PI-algebra has integral exponential growth – the PI-exponent of the
algebra. Later chapters further apply these results to subjects such
as a characterization of varieties of algebras having polynomial
growth and a classification of varieties that are minimal for a given
exponent. Results are extended to graded algebras and algebras with
involution.
The book concludes with a study of the numerical invariants and
their asymptotics in the class of Lie algebras. Even in algebras that
are close to being associative, the behavior of the sequences of
codimensions can be wild.
The material is suitable for graduate students and research
mathematicians interested in polynomial identity algebras.
Readership
Graduate students and research mathematicians interested in polynomial identity algebras.
Reviews & Endorsements
Written by two of the leading experts in the theory of PI-algebras, the book is interesting and useful.
