A. Mednykh, Automorphism groups and branched coverings of graphs

New channel Dubrovinlab: title sample judged 'pick' (Almost entirely genuine graduate-level math seminars and lecture series, but a few items like 'Kostroma-open' chess/game); passed a second screen for sellers/exam-prep/re-uploads; 3 of 3 sampled transcripts showed teaching, 0 not; titles picked one by one, checked strictly; oEmbed verified.
