Schur analysis originates with a 1917 paper by Schur where he associated
to a function analytic and contractive in the open unit disk a sequence,
finite or infinite, of numbers in the open unit disk, called Schur
coefficients. In signal processing, they are often called reflection
coefficients. Under the word "Schur analysis" one encounters a variety
of problems related to Schur functions such as interpolation problems,
moment problems, study of the relationships between the Schur
coefficients and the properties of the function, study of underlying
operators and others.
This volume is almost entirely dedicated to the analysis of Schur and
Carathéodory functions and to the solutions of problems for these
classes.
