Russian Mathematician - Olga AleksandrovnaLadyzhenskaya

Olga AleksandrovnaLadyzhenskaya is a well known Russian mathematician. She is fondly known for her contribution and works in the field of partial differential equations, fluid dynamics, and the finite difference method for the Navier–Stokes equations. For her immense contribution she received the Lomonosov Gold Medal in the year 2002.

She has also authored more than 200 hundred scientific works, inclusive of six monographs. She was born and brought up in the small town of Kologriv, and is the daughter of a mathematics teacher. She drew the inspiration of becoming a mathematician from her father. In the year 1937, her father was arrested by the NKVD and was executed as an "enemy of the people". She completed her high school in the year 1939 but unfortunately she could not be admitted to Leningrad University due to her father’s status. Resultantly, she took admission in the Moscow University in 1943 and graduated in the year 1947. She completed and presented her doctoral thesis in the year 1953. She later took up the teaching profession and started teaching at the university in Leningrad and then at the Steklov Institute. She has provided the first rigorous proofs of the convergence of a finite difference method for the Navier–Stokes equations. She has studied at the Ivan Petrovsky and was conferred with the Lomonosov Gold Medal in the year 2002. She was also honoured with the the John von Neumann Lecture Prize in the year 1998. She was also on the shortlist for potential recipients for the 1958 Fields Medal, but it was ultimately awarded to Klaus Roth and René Thom. Some of the famous publications in the name of Ladyzhenskaya are The Mathematical Theory of Viscous Incompressible Flow, Mathematics and Its Applications; Linear and quasi-linear equations of parabolic type; Linear and Quasilinear Elliptic Equations; The Boundary Value Problems of Mathematical Physics, Applied Mathematical Sciences; Attractors for Semigroups and Evolution Equations etc. Throughout her lifetime, she has won numerous awards namely P. L. Chebyshev Prize; USSR State Prize (1969); Kovalevskaya Prize (1992); Lomonosov Gold Medal (2002); and Prize of the Government of St. Petersburg and St. Petersburg Scientific Center RAS named after A. Ioffe. As a tribute for her extraordinary contribution, on 7 March 2019, which is the 97th anniversary of Ladyzhenskaya's birth, Google has released a Google Doodle commemorating her. The comment alongside the doodle reads a s follows, "Today’s Doodle celebrates Olga Ladyzhenskaya, a Russian mathematician who triumphed over personal tragedy and obstacles to become one of the most influential thinkers of her generation”.
