From a channel Lumen includes in full: This is the IMSc Chennai lecture archive. Nearly every upload is a full-length course lecture or research seminar in mathematics, theoretical computer science, physics or computational biology, confirmed by transcripts on LP rounding, graph polynomials, line bundles, epigenetics and the hierarchy problem. Unpolished filename titles are uninformative but not clickbait. The only non-teaching item seen is a short institute introduction video, which the title patterns catch.
