Math Material
All the material shared in this section is not mine and is shared by the mentioned authors in their webpages. The only objective of this page is to provide useful and free-access material for a complete and deep understanding of Math. I'm probably not aware of many good lecture notes/courses, so feel free to send me additional references to add!
