  I give a survey of joint work with Henrik Schlichtkrull on the induction of
certain relations among (partial) Eisenstein integrals for the minimal
principal series of a reductive symmetric space. I explain the application of
this principle of induction to the proofs of a Fourier inversion formula and a
Paley-Wiener theorem. Finally, the relation with the Plancherel decomposition
is discussed.
