Do primary/scholarly sources confirm that Mekh-mat's 'coffin problems' were deliberately unsolvable problems used to fail Jewish applicants?

Short answer: yes to "deliberately used to fail Jewish applicants," with strong Tier-1 sourcing on that part; no (or overstated) on "unsolvable." Multiple independent, named, scholarly primary accounts -- by mathematicians who were themselves either applicants, examiners' contemporaries, or direct participants -- confirm that Moscow State University's Mekh-mat oral entrance exams used a specific, deliberately selected class of very hard problems ("coffins" / "killer" / "murderous" problems) as an admissions weapon disproportionately against Jewish applicants. But none of the primary sources call the problems literally unsolvable. They are uniformly described as extremely difficult problems that DO have elementary solutions -- solutions that are just very hard to find -- which is precisely what made them useful to the examiners: a rejected student who found no solution had, technically, failed a solvable problem, so there was no obvious basis for appeal. The word "unsolvable" in the existing vault claim-note's title overstates what the sources say.

Claim: A. Shen's 1994 first-person account documents that Mekh-mat examiners deliberately chose specially hard "murderous" problems as an admissions weapon, with named examiners, applicants, and years -- but the problems had solutions, only very hard-to-find ones

Claim type: technical-mechanism (how the discrimination was actually implemented) + historical (named specifics). Floor: Tier 1-2 required for the mechanism; cleared.

A. Shen entered the Mekh-mat as a student in 1974, began graduate study there in 1979, completed it in 1982, and taught in Soviet mathematical schools from 1977 onward -- he is a direct participant-witness, not a secondary reporter. His 1994 Mathematical Intelligencer Opinion piece states that alongside procedural harassment (long waits, hostile appeal hearings, arbitrary marking), the examiners' key tool was "the choice of problems": applicants flagged for rejection were given a different, much harder set of questions than everyone else. Shen lists roughly twenty of these "murderous" problems verbatim, each dated and attributed to a named examiner (e.g. "Maksimov, Falunin, 1974"; "Podkolzin, 1978"; "Fedorchuk, 1979; Filimonov, Proshkin, 1980"), and states their difficulty was comparable to All-Union Mathematical Olympiad problems -- citing one 1985 olympiad problem that only 6 of 100 competitors solved. He introduces this list with: "Now the 'murderous' problems."

Shen does not describe the problems as unsolvable. They have solutions -- the difficulty is finding them under oral-exam pressure, with no warning that this "different" tier of problem had been substituted in.

Claim: Kanevskii & Senderov's data, reproduced in Shen's account, show a large admission-rate gap between non-Jewish-lineage and Jewish-lineage Mekh-mat applicants despite comparable or better olympiad performance by the latter group

Claim type: quantitative. Floor: Tier 1-2 required. Cleared via Shen's own Tier-1 reproduction, with a caveat below.

Statisticians B.I. Kanevskii and V.A. Senderov compiled, in 1979, exam and admission outcomes for graduates of six named Moscow mathematical schools, split into two groups: "First group" (47 students, no Jewish parent or grandparent) and "Second group" (40 students, at least one Jewish parent or grandparent). Shen reproduces their table for Mekh-mat: the Second group won more total olympiad prizes (48 vs. 26) and had more multiple olympiad winners (11 vs. 4) than the First group, but the Second group's admission rate was 6 of 40 (15%) against the First group's 40 of 47 (85%). Shen presents comparable, similarly lopsided figures for two other institutes (MIFI: 26/54 vs. 3/29; MFTI: 39/53 vs. 4/32).

source: same Shen 1994 article as above. source_quote (grounded): "One group of 47 consisted of students" [whose parents and grandparents were not Jews; introducing the table]. Caveat: the underlying data-collection itself is Kanevskii and Senderov's, "Intellectual Genocide: examinations for Jews at MGU, MFTI and MIFI" (Moscow, Samizdat, 1980) -- an unrefereed, self-published underground document that this capture did not independently locate or fetch. The numbers above are sourced here only as reproduced inside Shen's own Tier-1, peer-venue account, not against the Kanevskii/Senderov original. [unverified-quant -- the reproducing source (Shen) is Tier 1, but the ultimate compiling document (Kanevskii & Senderov 1980 samizdat) has not itself been located/verified this session].

Claim: A. Vershik's independently-authored, co-published 1994 account corroborates that the admissions committees' aim was specifically to limit Jewish (and other undesired) admissions

Claim type: historical/definitional (states the discriminatory objective; does not by itself establish the "coffin problem" mechanism, which is Shen's contribution). Floor: Tier 3-4 acceptable for uncontested historical framing; this clears Tier 1 anyway.

A. Vershik's companion Opinion piece, printed immediately before Shen's in the same Mathematical Intelligencer issue, states that the admissions committees' goal -- alongside excluding "political pariahs" -- "seems to have been to limit the admission of Jews and members of certain other national minorities." This is a second, independently-authored primary account (Vershik, not Shen) confirming the discriminatory intent, corroborating rather than merely repeating Shen's account, and appearing in the same refereed venue in the same month.

source: A. Vershik, "Admission to the Mathematics Faculty in Russia in the 1970s and 1980s," The Mathematical Intelligencer 16, no. 4 (1994). Same fetch as above: https://www.lirmm.fr/~ashen/springer-published/1994-4-entrance-exams.pdf (sha256 8062e48587fef843a8904504671fd96a8838ed03b618bb4434e4c80d98ed3e0a). source_quote (grounded): "seems to have been to limit the admission of Jews."

Claim: Two further, differently-authored and differently-venued sources -- Khovanova's own testimony and Saul's account in Notices of the AMS -- independently confirm the same mechanism, satisfying "do primary/scholarly sources confirm" with more than a single-source concentration

Claim type: historical/definitional, corroboration-status claim. Floor: Tier 3-4 acceptable; both sources here clear Tier 1-2.

Tanya Khovanova -- a member of the USSR's 1975 International Math Olympiad team, later a mathematician at MIT -- writes in first person, on her own site, that Mekh-mat "had at that time been actively trying to keep Jewish students (and other 'undesirables') from enrolling," using "a different set of problems" that were "carefully designed to have elementary solutions (so that the Department could avoid scandals) that were nearly impossible to find." She and her Olympiad teammates were asked by math teacher Valera Senderov in 1975 to help solve a smuggled list of these problems for use in coaching Jewish applicants; her team of eight solved only half in a month. This is independent of Shen (a different applicant/witness, a different venue, a different year of first contact with the material), though it cites Shen's and Vershik's articles as the documented background.

Mark Saul's "Kerosinka" piece in Notices of the AMS (1999) is a secondary account by a named mathematician-editor, built on interviews (he thanks Edward Frenkel, Dmitri Fuchs, and I.M. Gelfand among others) and citing Shen and Vershik directly. It narrates one detailed case (a 1984 applicant, "Edik" -- later identified as Edward Frenkel) in which examiners rejected every answer, including a definition of a circle marked wrong for omitting the word "all," and then privately advised the student to apply instead to the "Kerosinka" (the Gubkin Institute for Petrochemical and Natural Gas Industry), one of several institutes that absorbed talent excluded from Mekh-mat.

Between Shen (Tier 1, direct participant), Vershik (Tier 1, direct participant, independently authored), Khovanova (Tier 1, direct participant, independent of both), and Saul (Tier 2, named author writing in a refereed venue, drawing on independent interviews), the core mechanism claim rests on four non-identical sources across three publication venues (Mathematical Intelligencer, personal site/arXiv, Notices of the AMS) authored by different people -- comfortably clearing both the sourcing floor and the single-source concentration cap for this vault.

source_quote (Khovanova, grounded against her own site): "These problems were carefully designed to have elementary solutions (so that the Department could avoid scandals) that were nearly impossible to find." source_quote (Saul, grounded against the AMS PDF): "The story is a familiar one" / "reasons were found not to admit" [them].
