Editorial summary

The public source identifies “Marc Yor” as french mathematician (1949-2014). This brief keeps that definition visible, then builds a research path around Marc, French and mathematician.

Editorial reviewA useful biographical orientation record, particularly for establishing names, roles and a first chronology. The current lead gives the account dated anchors—1949, 2014, 1981, 1992—that can be checked directly. The linked authority record independently contributes the date 1949-07-24. Its value is orientation rather than verdict, with Marc, French and mathematician providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Marc Yor”, the useful work is to connect “french mathematician (1949-2014)” to the records capable of establishing context and consequence.

Evidence profile

The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Sep 2, 2026. The linked authority identifier is Q1892870. VIAF identifies the subject as 2533846. The Library of Congress control number is n79028552. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1949, 2014, 1981 and 1992.

Critical limits

Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
