The existence of hard oral problems is uncontested, but the load-bearing 'deliberately unsolvable' + 'selectively applied to Jewish applicants' framing is a discrimination-mechanism claim that the sourcing floor wants at Tier 1–2. Strong scholarly primaries exist (Vershik; A. Shen; Shifman's *You Failed Your Math Test, Comrade Einstein*). Verification routed to [[question-verify-mekh-mat-coffin-problems-primary-sources]]."

During the 1970s and 1980s, the Faculty of Mechanics and Mathematics
(Mekh-mat) at Moscow State University is reported to have used its oral entrance
examinations as an instrument of discrimination: examiners posed problems —
later nicknamed "coffins" (гробы) — that were elementary-looking but in practice
extremely hard or effectively unsolvable within the exam, and reserved them for
applicants the faculty wished to reject, disproportionately Jewish applicants
and others deemed undesirable. Because the oral format left no written record
and admitted subjective grading, it could enforce an informal quota while
remaining deniable.

This admissions-level mechanism is the institutional counterpart to the
individual-exclusion episode in
[[claim-pontryagin-used-committee-vote-to-help-block-margulis-1978-fields-medal-travel]]:
the same milieu that could bar a Fields Medalist from traveling could also keep
talented students out of the lecture hall in the first place. Such exclusion is
repeatedly named as a political-push driver of the 1970s–80s Jewish-
mathematician emigration wave — the precursor to the 1990s economic-push story
the vault treats in
[[claim-soviet-emigre-career-premium-was-structural-not-ability]] and
[[claim-soviet-scientists-immigration-act-1992-exceptional-ability-waiver]].

The claim is recorded here from a Tier-4 aggregator and paraphrase only. Its
core is well documented in the scholarly literature (A. Vershik and A. Shen on
the Mekh-mat entrance exams; M. Shifman's collected volume), and pulling one of
those primaries — with an example "coffin" problem and named testimony — is what
would move the note off `seedling`. That verification is routed to
[[question-verify-mekh-mat-coffin-problems-primary-sources]].
