Part A of this article is devoted to the general investigation of the
gravitational-wave emission by post-Newtonian sources. We show how the
radiation field far from the source, as well as its near-zone inner
gravitational field, can (in principle) be calculated in terms of the matter
stress-energy tensor up to any order in the post-Newtonian expansion. Part B
presents some recent applications to the problems of the dynamics and
gravitational-wave flux of compact binary systems. The precision reached in
these developments corresponds to the third post-Newtonian approximation.Comment: Plenary lecture given at the 16th International Conference on General
