google doodle honours mathematician Olga Ladyzhenskaya on her 97th birthdayWho is Olga Ladyzhenskaya? Four things you didn't know about the influential mathematician . . . . . . . . . 3. Her work’s practical applications remain useful to this day Ladyzhenskaya made valuable contributions to the field of fluid dynamics. Her research continues to impact oceanography, cardiovascular science, aerodynamics, and weather forecasting. ‘’She was perhaps the premier worker on the Russian side,’’ Dr Marshall Slemrod, a mathematician at the University of Wisconsin, told The New York Times when Ladyzhenskaya died at the age of 81. ‘’If you believe your weather forecast, you have to solve the exact equations that she studied.’’ . . . . https://www.independent.co.uk/news/science/olgaladyzhenskayagoogledoodlewhodeathmathrussiaa8811141.html Olga Aleksandrovna Ladyzhenskaya (Russian: Óльга Алекса́ндровна Лады́женская; 7 March 1922 – 12 January 2004) was a Russian mathematician. She was known for her work on partial differential equations (especially Hilbert's nineteenth problem) and fluid dynamics.[1] She provided the first rigorous proofs of the convergence of a finite difference method for the Navier–Stokes equations. She was a student of Ivan Petrovsky[2] and was awarded the Lomonosov Gold Medal in 2002. Publications Ladyzhenskaya, O. A.
