Grigory Margulis

Soviet-born mathematician awarded the Fields Medal at the 1978 International Congress of Mathematicians in Helsinki for his work on discrete subgroups of Lie groups, ergodic theory, and combinatorics — but barred from traveling from the USSR to receive it in person, with Jacques Tits accepting on his behalf.

Matters to this vault as the figure at the center of its Soviet-antisemitism institutional-politics cluster: the vault's evidence for his exclusion, and for who within Soviet and IMU institutions opposed his selection or blocked his travel, spans three existing claim-notes without, until now, a hub tying them together.
