Documented path
Born in Khabarovsk, Russia, Zelmanov studied at Novosibirsk State University, completing his PhD in 1980 at age 25.
Born in Khabarovsk, Russia; family background not documented.
Professor of Mathematics at UC San Diego; Fields Medalist (1994).
Where the conditions came from
Each is placed on a −1 to 3 scale from documented evidence, and the three are never added together. A combined total would rank Efim Zelmanov against other people. Held apart, they explain why this path ran differently from another one—which is the only comparison this project supports.
The marble itself
+2Tailwind
What capability, drive, or early skill is documented in the person rather than their surroundings?
Showed impressive mathematical abilities in school. Entered Novosibirsk State University at 17, completed PhD at 25. Strong early ability but no specific prodigy-level competition evidence.
Where it was dropped
0Neither way
What money, family standing, network, or permission was already in place before the work began?
Father was a railway transport engineer, mother was a school librarian. Ordinary Soviet family in Khabarovsk, then Novosibirsk. No special family advantages or academic connections.
The shape of the track
+2Tailwind
What place, timing, institution, or peer group made the next step available?
Novosibirsk State University, part of the strong Soviet mathematics tradition at Akademgorodok. Supervised by prominent algebraists Shirshov and Bokut. The Novosibirsk math ecosystem was significant for algebra.
A −1 is a documented headwind, not a missing value; a 0 means the sources record nothing notable either way. Annotation confidence: Medium. These are analyst readings of what the sources record, not measurements of merit, talent, or effort. The twenty-two scored dimensions remain available inside the deeper research detail.
What moved through the conditions
Silence in a biography is not evidence that perseverance was absent.
A successful-only archive cannot recover all encounters, avoided setbacks, or alternative outcomes.
Strongest documented signals: Elite institution pipeline, Frontier geography, Dedicated mentor / coach.
Describes the starting position, not what the person later made of it.
Strongest observed levers: Scarce skill depth, Domain proximity, Started serious reps before 20.
Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
The timeline below shows the sequence of work and transitions around the selected early milestone. It is evidence of a path, not proof that every step was necessary.
Legendary or globally iconic career standing. The tier summarizes documented career recognition through the data cutoff—not Efim Zelmanov's worth or future potential.
Question four · where did the leverage come from?
Each non-zero lever gets a best-supported origin, evidence signals, and confidence. Unresolved is the honest default when the biography cannot distinguish self-built, advantage-enabled, earned, external, or mixed.
One or more documented starting advantages plausibly enabled this lever.

A structural wave is external to the person, even when their position improved access to it.
This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Efim Zelmanov's outcome attributable to any origin.
Structural luck, Encounter luck, Event luck, Outcome variance can change every arrow in the path. This successful-only dataset cannot observe the near-identical paths that did not break through, so luck stays visible and unscored.
Multiplying capacity documented later in the path. Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
Access or conditions documented near the beginning of the path. Zero means "no clear evidence in reviewed sources," not "advantage was absent."
Not documented in reviewed sources.

Zelmanov completed his PhD at Novosibirsk State University in 1980 at age 25. His solution of the restricted Burnside problem earned him the Fields Medal in 1994.
