Grothendieck’s Mysterious Reference Explained

ag.algebraic-geometryderham-cohomologyreference-request

These days I found a mysterious page on Google books describing a book entitled On the De Rham cohomology of schemes by Grothendieck, Coates, and Jussila.

At once I thought this was an error and Google books had miss-indexed Exposé IX of Dix Exposés sur la Cohomologie de Schémas. However, the references diverge both in their titles:

Crystals and the De Rham Cohomology of Schemes

vs.

On the De Rham cohomology of schemes,

as well as their numbers of pages (53 in Dix Exposés vs. 106 in this reference).

The book is even cited in Cisinski 's Habilitation thesis as

[Gro66] A. Grothendieck « On the de Rham cohomology of schemes » Publ. Math. IHES 29 (1966), p. 93–103.

Maybe this is "On the de Rham cohomology of algebraic varieties", but again, the references diverge in page number and title.

So, does this book really exists, and, if so, is it available anywhere?

Best Answer

I think your hunch is correct that Google is in error, and that "Crystals and the de Rham cohomology of schemes" refers to the article in Dix Exposés. I doubt there is a book by the same name and author. There is also "On the de Rham cohomology of algebraic varieties" but that's different. The first is a long proposal for crystalline cohomology (which hadn't been developed at that point), and the second is an extract from a letter to Atiyah giving a proof of the algebraic de Rham theorem. Does that help?
