Advanced online courses for different subjects During the pandemic, almost all the courses (basic or advanced) have been moved online instead of in-person. I was wondering if anyone knows online complete new courses for

*

*Measure theory;

*Set theory;

*Descriptive set theory.

Any idea will be appreciated greatly.

A few years ago, IMPA recorded lectures on Measure Theory, which you can find here. You can find the auxiliary notes here: https://w3.impa.br/~landim/Cursos/MT.pdf
While I have not seen the measure theory lectures myself, I did follow the probability theory lecture series they recorded, which were of superb quality. I expect the same for this lecture series.
