  In an earlier paper the author proved one divisibility of Perrin- Riou's
Iwasawa main conjecture for Heegner points on elliptic curves. In the present
paper, that result is generalized to abelian varieties of GL2-type (i.e.
abelian varieties with real multiplication defined over totally real fields)
under the hypothesis that the abelian variety is associated to a Hilbert
modular form via a construction of Zhang.
