# Note Index

I make public some pieces of paper I collect and write while studying some topic. They are not meant to be definitive and many of them do not contain original material. Think of these as atomic ideas that I am happy to share and discuss.

In academic work, if you need to refer to these notes, please cite them as you would cite a blog post. You may also want to take a snapshot at the Internet Archive project.
