Harmonic analysis From Wikipedia, the free encyclopedia Jump to: navigation search Harmonic analysis is the branch of mathematics that studies the representation of functions or signals as the superposition of basic waves . It investigates and generalizes the notions of Fourier series and Fourier transforms . The basic waves are called " harmonics ", hence the name "harmonic analysis," but the name "harmonic" in this context is generalized beyond its original meaning of integer frequency multiples. In the past two centuries, it has become a vast subject with applications in areas as diverse as signal processing quantum mechanics , and neuroscience . The classical Fourier transform on R n is still an area of ongoing research, particularly concerning Fourier transformation on more general objects such as tempered distributions . For instance, if we impose some requirements on a distribution f, we can attempt to translate these requirements in terms of the Fourier transform of f. The Paley-Wiener theorem is an example of this. The Paley-Wiener theorem immediately implies that if f is a nonzero distribution of compact support (these include functions of compact support), then its Fourier transform is never compactly supported. This is a very elementary form of an

Abstract Harmonic Analysis Abstract Harmonic Analysis refers to all aspects of analysis on locally compact groups. This class of groups is particularily suitable for analysis due to the existence of a left (or a right) invariant measure, called Haar measure, on any such group. Among other things, Haar measure is a basic tool in developing the representation theory of locally compact groups. The class of locally compact groups is large enough to encompass many/most of the topological groups that arise in physics, geometry, number theory and other areas of mathematics and the natural sciences. Moreover, any abstract group is a topological group when endowed with the discrete toplogy. In all these examples of interesting groups, the representations of the groups have meaningful interpretations and applications. I am particularly interested in the dual spaces of locally compact groups and the influence that the topological properties of the dual space have on the analysis of functions on the group. If G is a locally compact group, the set of equivalence classes of irreducible unitary representations of G is denoted G^ and is called the dual space of G. There is a natural topology on G^ which usually fails to be Hausdorff. It is the non-Hausdorff character of most dual spaces that leads to much of the fun.

E. Johnson proved that a locally compact group $G$ is amenable if and only if certain Hochschild cohomology groups of its convolution algebra $L^1(G)$ vanish. Similarly, $G$ is compact if and only if $L^1(G)$ is biprojective: In each case, a classical property of $G$ corresponds to a cohomological propety of $L^1(G)$. Starting with the work of Z.-J. Ruan in 1995, it has become apparent that in the non-commutative setting, i.e. when dealing with the Fourier algebra $A(G)$ or the Fourier-Stieltjes algebra $B(G)$, the canonical operator space structure of the algebras under consideration has to be taken into account: In analogy with Johnson's result, Ruan characterized the amenable locally compact groups $G$ through the vanishing of certain cohomology groups of $A(G)$. In this paper, we give a survey of historical developments, known results, and current open problems. Comments: 12 pages; a survey article; typos removed, references updated

Peter on the theory of representations of compact groups (cf. Representation of a compact group ) and of L.S. Pontryagin on the theory of characters of locally compact Abelian groups (cf. Character of a group ), posed the problem of the natural limits of the main results of classical harmonic analysis. This problem is based on the following interpretation of an ordinary Fourier series in complex form.
