Olga Ladyzhenskaya is remembered in mathematics for work the next generation could build on.
The record lists Olga Ladyzhenskaya as Russian mathematician (1922–2004).
Olga Ladyzhenskaya was born at Kologriv in 1922. Her recorded nationality is Russia. She studied at MSU Faculty of Mechanics and Mathematics and Saint Petersburg State University.
Twentieth-century mathematics became abstract and highly specialised, and its methods reached into physics, economics and computing.
Her academic posts were held at Saint Petersburg State University and St. Petersburg Department of Steklov Institute of Mathematics of Russian Academy of Sciences.
The recorded fields of work are partial differential equation, theory of differential equations and mathematical analysis.
Among her principal contributions are Ladyzhenskaya's inequality and Ladyzhenskaya–Babuška–Brezzi condition. Mathematics accumulates without discarding: a proof from two thousand years ago is still a proof.
The honours record reads: USSR State Prize (1969), Lomonosov Gold Medal (2002), Order of Friendship (1999) and John von Neumann Prize (1998).
That the work was done from Russia matters: mathematical training, institutions and the language of publication have never been evenly distributed.
Olga Ladyzhenskaya died in 2004, aged 82. The proofs remain, and a proof does not decay - which is the particular permanence mathematics offers.
