A review on anomaly cancellation in string theory (2025)

It was a 3-hour talk in a mini-workshop organized by young postdocs in Japan, held in Hongo on September 25, 2025.

I welcome corrections and any other comments on the materials below:

• The lecture notes are available here (last update: September 24, 2025).
• The accompanying Mathematica file is available here.
• Video Part I, Video Part II (The microphone died for a few minutes in the second part, sorry.)
