Riguardo questo articolo

The first systematic theory of generalized functions (also known as distributions) was created in the early 1950s, although some aspects were developed much earlier, most notably in the definition of the Green's function in mathematics and in the work of Paul Dirac on quantum electrodynamics in physics. The six-volume collection, Generalized Functions, written by I. M. Gelfand and co-authors and published in Russian between 1958 and 1966, gives an introduction to generalized functions and presents various applications to analysis, PDE, stochastic processes, and representation theory.The unifying idea of Volume 5 in the series is the application of the theory of generalized functions developed in earlier volumes to problems of integral geometry, to representations of Lie groups, specifically of the Lorentz group, and to harmonic analysis on corresponding homogeneous spaces. The book is written with great clarity and requires little in the way of special previous knowledge of either group representation theory or integral geometry; it is also independent of the earlier volumes in the series. The exposition starts with the definition, properties, and main results related to the classical Radon transform, passing to integral geometry in complex space, representations of the group of complex unimodular matrices of second order, and harmonic analysis on this group and on most important homogeneous spaces related to this group. The volume ends with the study of representations of the group of real unimodular matrices of order two.

Riassunto

Gel'Fand, Graev, and Vilenkin originally intended the material on the theory of representations to be in some chapters in the fourth of five volumes, but decided to add a volume devoted to it entirely. They find that representation theory is based on what they call integral geometry, that is, geometry that involves the transition from functions defined on one set of geometrical objects--for example on the points of some linear surface--to functions defined on some other set--for instance on the lines generating this surface. They accomplish the transition from one space to the other with the simultaneous transformation of the function defined on it. Annotation ©2016 Ringgold, Inc., Portland, OR (protoview.com)
