The principal error in this paper
was the incorrect claim that Iwasawa's sufficient criterion for a compact L-module to be torsion — that its group of
coinvariants be finite — generalizes to the non-abelian situation. A correct criterion,
involving the Euler characteristic, has since been found by Susan Howson.
Several proofs based on the fallacious criterion are replaced by alternative
proofs in the Correction. However, in the absence of a valid criterion,
it is impossible to justify the claim that certain modules constructed from
Selmer groups of elliptic curves are torsion L-module. Using the Euler characteristic criterion, Coates and Howson
found the first examples of torsion modules over the Iwasawa algebra of GL(2,Zp) coming from Selmer groups of elliptic curves.
To my knowledge,the remainder of
the results of this paper are correct, when taken in conjunction with the
correction. This includes some of the basic structural theory of compact L-modules in the non-abelian case, the proof
that the L-module constructed from ideal class groups
(the direct analogue of the module studied by Iwasawa) is torsion, and certain
control theorems.

the main result is false for every semisimple p-adic group.

A rumor has been circulating to the
effect that one of the statements used in this article was not proved until
several years later, and that the proofs are
therefore incomplete. Apparently this is based on a misunderstanding. The
statement in question, as far as I can tell, is 3.6.2, the claim that the
antiholomorphic highest weight module for Sp(2n) is
irreducible down to weight n/2. This is of course a simple consequence of
the unitarity of the module (cited in 3.6.1), the fact that it is generatedby a
highest weight vector, and the well known fact that any submodule is generated
by highest weight vectors. If there is anything more to the rumor I
don't know what it is.

The argument in 3.5 of this mainly
expository paper, concerning jet bundles, is nonsense. A correct argument
is given in the subsequent articles.
[13] Harris, M.: Arithmetic vector
bundles and automorphic forms on Shimura varieties. I. Inventiones Math. 82, 151-189 (1985).
The term "arithmetic vector
bundle" has since been replaced by "automorphic vector
bundle". The argument in (3.6.7), deriving existence of a model over a number field of an "absolutely
arithmetic" automorphic vector bundle by means of a cocycle condition
involving Aut(C),
needs further justification. [SEE NOTE BELOW.] A simpler alternative is to
observe that a quotient of the canonical principal bundle I(G,X) by a finite
subgroup C of the center of G is already
defined over the reflex field E(G,X). One can take C to be the
intersection of the center of G with the derived subgroup Gder.
Indeed, the fact that the quotient of I(G,X) by the center of G is defined over
E(G,X) follows from Proposition 3.7, whereas the fact that the quotient by Gder
is defined over E(G,X) is a conseqence of the theory for tori. Since
finite étale covers are defined over finite algebraic extensions, one sees
immediately that I(G,X) is defined over some number field, as are the Hecke
correspondences on I(G,X). One can then replace the cocycle
for Aut(C) by a continuous cocycle on the Galois group
of the algebraic closure of Q. A complete argument may be given elsewhere.
NOTE ADDED MARCH 21, 2008:
After rereading Shimura's original proof of the existence of canonical models
using cocycles on Aut(C) [Shimura, Annals of Math., 83 (1966) 294-338] in the light of its reformulation by
Varshavsky [Appendix to Selecta Math., 8 (2002) 283-314], I am now convinced that the argument in (3.6.7)
is essentially correct.
The argument proceeds by constructing a cocycle on Aut(C) with values in Gm that is shown to be effective for
descending to
an appropriate reflex field an automorphic vector bundle on the Shimura variety
attached to a torus. It thus necessarily
satisfies the required continuity property. All that is missing from the
proof is acknowledgment of of this requirement.

Cohomologie de Dolbeault à croissance logarithmique à l'infini. C. R. Acad. Sci.

302, 307-310 (1986).
José Ignacio Burgos pointed
out in 1997 that the argument in Griffiths-Harris, used to extend the Poincaré
Lemma with logarithmic singularities from the one-dimensional case to the
general case, does not apply in the present situation. Briefly, the
Dolbeault complex defined in this paper consists of forms w which, together with their antiholomorphic
derivatives, satisfy logarithmic growth conditions in the neighborhood of a
divisor with normal crossings. However, the Griffiths-Harris argument
introduces additional holomorphic derivatives, which may not belong to the
original complex. The quotation
should have been of the argument used by Borel in reference [1], which is based
on integration rather than differentiation.
As noted in [19], and as observed
independently by Burgos, one can actually reprove the one-dimensional Poincaré
lemma with logarithmic singularities for forms all of whose derivatives,
holomorphic as well as anti-holomorphic, satisfy the growth conditions; this is
even necessary if one wants to obtain Lie algebra cohomology complexes to
calculate the cohomology of Shimura varieties. A complete proof of this
fact, and the correct deduction of the higher-dimensional case, was published
in [42], in response to Burgos' comment.

The last section of this article
assumes the extension of the techniques of [22] to general totally real
fields. At the time of publication, I was under the mistaken impression that
the Siegel-Weil formula for the central value of the Eisenstein series, proved
by Kudla and Rallis, extended in a simple way to the symplectic similitude
group GSp(6). In fact, the extension proposed in [22] only works over Q. A
correct Siegel-Weil formula for similitude groups is proved in [49]. Thus
the proofs in this article are now complete.

The relation of CM periods to
special values of L-functions of Hecke characters, obtained in general by
Blasius, is quoted on numerous occasions in this article. Unfortunately,
it is quoted here, as in the appendix to [22], with a sign mistake. The
final formulas are indifferent to the choice of sign, so no harm is done.
The mistake is corrected in the introduction to [35], whose results depend on
the correct choice of sign.

has pointed out a group of related errors in this article, as well as an
ambiguity and a few arguments based on constructions for which there are not
references in the literature. The
main point is that some of the modules only have models over finite extensions
of their fields of coefficients.
This has no bearing on applications to special values of L-functions,
but the statements have to be corrected.
