# Asymptotic Representation Theory of the Symmetric Group and its Applications in Analysis

Share this page
*S. V. Kerov*

This book reproduces the doctoral thesis written by a remarkable mathematician,
Sergei V. Kerov. His untimely death at age 54 left the mathematical community
with an extensive body of work and this one-of-a-kind monograph. In it, he gives
a clear and lucid account of results and methods of asymptotic representation
theory. The book is a unique source of information on the important topic of
current research.

Asymptotic representation theory of symmetric groups deals with problems of two
types: asymptotic properties of representations of symmetric groups of large
order and representations of the limiting object, i.e., the infinite symmetric
group. The author contributed significantly in the development of both
directions. His book presents an account of these contributions, as well as
those of other researchers.

Among the problems of the first type, the author discusses the properties of
the distribution of the normalized cycle length in a random permutation and the
limiting shape of a random (with respect to the Plancherel measure) Young
diagram. He also studies stochastic properties of the deviations of random
diagrams from the limiting curve.

Among the problems of the second type, Kerov studies an important problem of
computing irreducible characters of the infinite symmetric group. This leads to
the study of a continuous analog of the notion of Young diagram, and in
particular, to a continuous analogue of the hook walk algorithm, which is well
known in the combinatorics of finite Young diagrams. In turn, this construction
provides a completely new description of the relation between the classical
moment problems of Hausdorff and Markov.

The book is suitable for graduate students and research mathematicians
interested in representation theory and combinatorics.
