Source-derived summary

Evgenii Mikhailovich Landis (Russian: Евгений Михайлович Ландис; 6 October 1921 – 12 December 1997) was a Soviet mathematician who worked mainly on partial differential equations.

Life

Landis was born in Kharkiv, Ukrainian SSR, Soviet Union. He was Jewish. He studied and worked at the Moscow State University, where his advisor was Alexander Kronrod, and later Ivan Petrovsky. In 1946, together with Kronrod, he rediscovered Sard's lemma, unknown in USSR at the time.

Later, he worked on uniqueness theorems for elliptic and parabolic differential equations, Harnack inequalities, and Phragmén–Lindelöf type theorems. With Georgy Adelson-Velsky, he invented the AVL tree data structure (where "AVL" stands for Adelson-Velsky Landis).

He died in Moscow. His students include Yulij Ilyashenko and Boris Katz.

Editorial summary

This brief starts where responsible research should: with the source description of “Evgenii Landis” as russian mathematician (1921–1997). Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA useful biographical orientation record, particularly for establishing names, roles and a first chronology. The current lead gives the account dated anchors—1921, 1997, 1946—that can be checked directly. The linked authority record independently contributes the date 1921-10-06. The account is most persuasive where Evgenii, Landis and Russian can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the people & ideas register because the source frames it as russian mathematician (1921–1997). Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated May 23, 2026. The linked authority identifier is Q92998. VIAF identifies the subject as 58033323. The Library of Congress control number is n84802837. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1921, 1997 and 1946.

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

Read biographical claims against dates, named institutions and the cited references. Distinguish a subject’s later reputation from evidence produced during their lifetime.
