Hasse = “le P. Adique, de l’Ordre des Diophantiens”

It contains this, seemingly opaque, paragraph: It was pretty easy to decode the date of the wedding “3 Cartember, year VI” to be June 3rd, 1939, and (a bit more difficult) the wedding place “the Principal Cohomology of the Universal Variety” as the l’église royale Notre-Dame du Val-de-Grâce in Paris. The identity of the celebrating... Continue reading ?

De Rham Cohomology is Functorial

Academics / Mathematics : The Unapologetic Mathematician

It turns out that the de Rham cohomology spaces are all contravariant functors on the category of smooth manifolds. We’ve even seen how it acts on smooth maps. All we really need to do is check that it plays nice with compositions. ...

Last time we’ve seen that on June 3rd 1939, the very day of the Bourbaki wedding, Malraux’ movie ‘L’espoir’ had its first (private) viewing, and we mused whether Weil’s wedding card was a coded invitation to that event. But, there’s...

Compactly Supported De Rham Cohomology

Academics / Mathematics : The Unapologetic Mathematician

Since we’ve seen that all contractible spaces have trivial de Rham cohomology, we can’t use that tool to tell them apart. Instead, we introduce de Rham cohomology with compact support. This is just like the regular version, except w...
