I typed these notes while I was a master student in Bordeaux. It goes without saying that all possible mistakes are entirely mine. If you spot some typo or inaccuracy, don’t hesitate to contact me.

Here’s a picture of me as an anteater, *oso hormiguero*,

Here are some of my photos from Central America.

It is actually a rather random word, similar to “abracadabra”,
that came to my mind when I was looking for a domain name. It comes
from a computer programming language named LISP, where
(cadadr x) = (car (cdr (car (cdr x)))). It was not intended to sound
like *cadavre* or anything like that and it is not my nickname
either.

Below I share for fair use some texts that I scanned myself or found in obscure places. I hope someone finds these useful and nobody objects.

- Michael Artin, Jean-Louis Verdier,
*Seminar on étale cohomology of number fields* - Spencer Bloch,
*The moving lemma for higher Chow groups* - Kazya Kato,
*p-Adic Hodge theory and values of zeta functions of modular forms* - Jean-Pierre Serre,
*Zeta and L functions* - Thomas Zink,
*Étale cohomology and duality in number fields*

Here are some links that I have collected mostly for myself.
