Apr 19, 2018 at 18:15 comment added Sylvain JULIEN As a side comment, I think it would be more than convenient to have an online automated translation service for users of the stackexchange network able to deal as accurately as possible with the different fields involved therein. Something like google translate but plugged in websites like MO that would provide an immediate and reliable translation of any document available online, taking into consideration the context (for example based on arxiv subfields of math for MO).

Apr 17, 2018 at 3:33 comment added user117832 Thank you so much for the comment! (I have also been reading your papers!) I actually just wanted to look at how he went about constructing the parallel forms.
Apr 16, 2018 at 20:43 comment added Robert Bryant Unfortunately, I could not locate my copy of Bonan's paper (which is a shame, since he gave it to me himself) and our library does not have it. I have asked them to retrieve a copy from another library. In the meantime, I looked at the review in MathSciNet, and it gave essentially the same account (in English) of the contents that I gave yesterday (but with a little more detail). When the library provides me with a copy, I'll report on whether it contains any additional results that were not mentioned in the MathSciNet review. Is there anything specific you are looking to find in the article?
Apr 15, 2018 at 20:05 comment added Robert Bryant I am pretty sure that I have a copy of Bonan's 3-page paper in my reprint files in my office. If you don't need a literal translation, I can write a short summary in English sometime tomorrow when I go in. My memory is that Bonan's main results are the construction of the parallel differential forms in each case and the sketch of the proof that such manifolds are Ricci flat. At that time, of course, no one knew whether any examples (even local ones) existed whose holonomy was the full group $\mathrm{G}_2$ or $\mathrm{Spin}(7)$.
Apr 15, 2018 at 6:41 comment added Ben McKay I am pretty sure there is no English translation.
Apr 15, 2018 at 6:35 comment added Carlo Beenakker there is no English translation of Comptes Rendus Hebdomadaires des Seances de l'Academie des Sciences Serie A , 1966, Vol. 262 (2), p.127

Apr 15, 2018 at 3:15 comment added Willie Wong it would be helpful for questions like this if you would include the full citation information of the paper. at the very least, author?
