京都大学理学研究科 数学特別講義（函数解析学）「作用素環と共形場理論」第1回 河東 泰之（東京大学大学院数理科学研究科 教授）2018年4月9日

Picked video by video from Kyoto U OCW (mixed channel): title plainly names a teaching subject. Channel transcript sample: All three samples are substantive academic lectures/seminar talks (IT management course, bio-sensing research seminar, language-education colloquium) rather than ceremonies or promos, supporting a pick verdict with per-video selection.
