Sergei Novikov

Soviet-Russian topologist (b. 1938), Fields Medalist (1970) for work in algebraic and differential topology, and later author of a pointed online memoir, Pontryagin: my comments concerning the worst period of his activity, recounting his own eyewitness view of Steklov Institute politics in the late 1970s and early 1980s.

Matters to this vault as the sole eyewitness source behind claim-pontryagin-used-committee-vote-to-help-block-margulis-1978-fields-medal-travel, the vault's sharpest reversal of Pontryagin's otherwise sympathetic portrait — and, on a 2026-08-24 direct re-read of his memoir, an instructive case of the gap between an eyewitness's decades-later memory of a document ("as far as I remember now") and a fresh transcription of it. His memoir also names a Keldysh–Vinogradov–Shafarevich "triangle" as the deeper institutional-politics thread behind the antisemitic campaign he describes, casting Ivan Vinogradov as the more central, KGB-linked orchestrator — a lead not yet independently corroborated.

• 2026-10-31: The same pont.pdf essay yields a second, distinct episode beyond the 24:0 vote quote: Novikov recounts a September 1979 Kiev conversation where Martin Kruskal, acting for a Western editorial board, showed him Pontryagin's reply to an "antipontryagin letter" containing roughly ten accusations — including that Pontryagin pressed the National Committee to vote against Margulis's Fields Medal and Congress attendance. Plausibly the same dispute underlying Pontryagin's unread 1979 Science reply, but not confirmed as the same document, and explicitly distinct from the collective, fifteen-signer 1978 ICM memorandum this promotion's other new notes investigate.
