Let G be a complex connected reductive group with simply connected der
ived group. Let H be a real form of G. Let z be a G-invariant differen
tial operator on the reductive symmetric space G/H. We give an explici
t sufficient condition for z to have an invariant fundamental solution
on G/H. (C) Academie des Sciences/Elsevier, Paris.
