We show that Arthur's Paley-Wiener theorem for K-finite compactly supported
smooth functions on a real reductive Lie group G of the Harish-Chandra class
can be deduced from the Paley-Wiener theorem we established in the more general
setting of a reductive symmetric space.
In addition, we formulate an extension of Arthur's theorem to K-finite
compactly supported generalized functions (distributions) on G and show that
this result follows from the analogous result for reductive symmetric spaces as
well.Comment: Latex2e, 28 pages, change of definition of space P^* on p. 17 + minor
