What follows is not a jab at the author of the document. I think it's really nice for an undergrad to be interested in this topic. It's very close to my field of research, and not something that an undergrad would typically know about. But why would you post someone's draft of a bachelor thesis here? If someone is really interested in intersection homology (and perverse sheaves!), here is a set of lecture notes (not written by me): https://webusers.imj-prg.fr/~bruno.klingler/cours/courspervers.pdf https://webusers.imj-prg.fr/~bruno.klingler/cours/coursperve...
