Induced Representations of Locally Compact Groups

"Locally compact groups arise in many diverse areas of mathematics, the physical sciences, and engineering and the presence of the group is usually felt through unitary representations of the group. This observation underlies the importance of understanding such representations and how they may be constructed, combined, or decomposed. Of particular importance are the irreducible unitary representations. In the middle of the last century, G.W. Mackey initiated a program to develop a systematic method for identifying all the irreducible unitary representations of a given locally compact group G. We denote the set of all unitary equivalence classes of irreducible unitary representations of G by G. Mackey's methods are only effective when G has certain restrictive structural characteristics; nevertheless, time has shown that many of the groups that arise in important problems are appropriate for Mackey's approach. The program Mackey initiated received contributions from many researchers with some of the mostsubstantial advances made by R.J. Blattner and J.M.G. Fell. Fell'swork is particularly important in studying Gas a topological space. At the core of this program is the inducing construction, which is a method of building a unitary representation of a group from a representation of a subgroup"--

Klappentext
A comprehensive presentation of the theories of induced representations and Mackey analysis applied to a wide variety of groups.

Zusammenfassung
Locally compact groups and their representation theory underlie areas such as relativity, quantum field theory, signal processing and medical imaging. All who are interested in the foundations of such subjects, as well as pure mathematicians working in harmonic analysis, will appreciate this comprehensive monograph.
