A Computation a Day
Punctured disks and punctured curves and cohomology, oh my! (Part II: cohomology with supports)
Punctured disks and punctured curves and cohomology, oh my! (Part I: the proper curve case)
This is the first in a series of posts whose goal is to compute the cohomology of the (several times) punctured closed -adic disk
as well as the cohomology of smooth (and some non-smooth) algebraic curves.
A computation a day: a pullback pushforward
In this post we compute the Galois representation where
is the natural inclusion and
is the inclusion of the origin.
A computation a day: the Brauer group of a number ring
In this post we compute the group where
is a number field.
A computation a day: compactly supported cohomology
In this post we compute the compactly supported cohomology of some simple varieties.
