#Excellence in her academics <\/b><\/strong><\/h3>\n After completion of graduation in 1947, Olga moved to Leningrad due to the family circumstances to become a postgraduate at the Leningrad State University.<\/p>\n
There she started with her long-standing friendship with Smirnov and became the in-charge of several branches of mathematics, hydrodynamics, seismology, and aerodynamics. These studies motivated her towards the Equations of Mathematical Physics.<\/p>\n
In that year, she married Andrei Kiselev who was the specialist in the number theory and history of mathematics.<\/p>\n
She did not take children because she wanted to devote her life to mathematics. In 1949, Olga defended the dissertation of her doctoral based on finite differences methods for Linear and linear systems.<\/p>\n
In this regard, she gave many efforts to prove the solubility of the boundary as well as initial boundary-based problems. Later on, Olga started with the mission of preparing for a diploma thesis on the problems that were suggested by Petrovsky.<\/p>\n
<\/b>#Acknowledgment of Olga Ladyzhenskaya work<\/h3>\n Her first book was published in 1953. The book is \u201cMixed Problems for a Hyperbolic Equation\u201d. The book contains knowledge about the finite difference method for proving theoretical results.<\/p>\n
It is mainly based on the solvability of initial boundary-value problems. The foundation is general second-order hyperbolic equations.<\/p>\n
In 1954, she became a teacher at the Leningrad State University and initially practiced as a researcher at the Steklov Mathematical Institute of the Academy of Sciences, USSR. Later on, she excelled with the equations of elasticity, the Schr\u00f6dinger equation, Maxwell’s equations, and the linearized Navier-Stokes equations.<\/p>\n
In 1961, another book was published \u201cThe Mathematical Theory of Viscous Incompressible Flow\u201d. This book proved to be an outstanding success.<\/p>\n
Olga and Nina Ural’tseva jointly wrote many papers for devoting to the investigation of quasilinear elliptic as well as parabolic equations of the second order.<\/p>\n
The implication of these papers was that the mid-1950s Olga and her students started marking advances in the field of boundary-value problems for quasilinear elliptic – parabolic equations.<\/p>\n
<\/noscript>The researchers could be fruitful in delivering a complete theory about the solvability of boundary-value problems. It also includes the uniformly parabolic as well as uniformly quasilinear elliptic second-order equations. The papers also gave way to the smoothness of generalized solutions.<\/p>\nWhat\u2019s most fascinating about her work is that one result was successful enough in yielding the solution of Hilbert’s 19th problem.<\/p>\n
She wrote around 250 papers in her life for which she had achieved recognition.<\/p>\n
The recognition mostly centred around solving partial differential equations (based on Hilbert’s nineteenth problem) as well as fluid dynamics. She was first to give the rigorous proofs of the convergence of Navier\u2013Stokes equations finite difference method.<\/p>\n
<\/b> Awards & Achievements of Olga Ladyzhenskaya<\/b><\/strong><\/h3>\n This section will give you the compiled information about the numerous awards and achievements in Ladyzhenskaya’s life.<\/p>\n

On 7 March 2019 was the 97th birth anniversary of Ladyzhenskaya. To pay homage to her contributions in the field of mathematics, the search engine Google laid an official release of the Google Doodle commemorating her. There was an accompanying comment that read about the Doodle celebration of the birth anniversary of Olga Ladyzhenskaya. It had mentioned the contributions of the Russian mathematician who triumphed over personal tragedy as well as huge obstacles to become influential thinkers of her generation.<\/p>\n
<\/b> Least known facts about Olga Ladyzhenskaya<\/b><\/strong><\/h2>\n <\/noscript><\/p>\n\n\n Her family ties had always tried to compel her away from pursuing her education. <\/b><\/strong><\/h3>\n<\/li>\n<\/ol>\n In fact, the reports suggest that AleksandrIvanovichLadyzhenskii, Ladyzhenskaya’s father was the major inspiration behind his daughter. He was the only one who had kickstarted Olga\u2019s interest in mathematics. He had tried his best to overcome prejudices of the society and inspire his daughter in getting educated.<\/p>\n
Ladyzhenskii passes away in October 1937, when Olga was only 15. He had suffered a tragic death in a Soviet torture chamber. All this happened because the Stalinist authorities had treated him. The proof of this record is the mathematics history archive, University of St Andrews, Scotland.<\/p>\n
She was a successful woman of her time who could secure a graduate degree from secondary school with excellent grades. But, the lesser-known fact is that Ladyzhenskaya was kept away from enrolling at Leningrad State University. It was a tragic part of her life where she had to constantly suffer the consequences of her father being considered an \u201cenemy of the nation\u201d.<\/p>\n
Breaking all obstacles, Olga taught at an orphanage. Then she proceeded further in teaching at a secondary school. After the completion of her tenure in this school, she entered Moscow State University in 1943.<\/p>\n
\n\n She had to suffer a lot for overcoming the political and social unrest prevailing in her country <\/b><\/strong><\/h3>\n<\/li>\n<\/ol>\n Throughout her life, Olga had to face political disturbances prevailing in the nation that hindered her devotion towards mathematics. It was a great obstacle in her research. She completed the thesis in 1951 but it could not be published until 1953( after the death of Joseph Stalin).<\/p>\n
When the communist rule of the country came to an end in 1989, Olga along with the other Russian mathematician’s friends got the freedom of travelling. Till that Olga could not manage at any cost to venture beyond Eastern Europe. She could attend only the international Congress of mathematicians in Edinburgh.<\/p>\n
She couldn’t even attend any event until 1988 when she was under the Soviet regime. It meant like Olga was unable to even meet another prominent scientist for the years. Those scientists were also not allowed to visit the union.<\/p>\n
\n\n Her work and practical applications become useful theses days. <\/b><\/strong><\/h3>\n<\/li>\n<\/ol>\n Olga had made her valuable contributions to fluid dynamics. The research continuously maintaining its impact on cardiovascular science, oceanography, aerodynamics, and weather forecasting to the present day. Dr. Marshall Slemrod, the mathematician at the University of Wisconsin that he was the premier worker on the Russian side. He also mentioned that if one wishes to go ahead with weather forecasting, that Candidate should solve the exact equations that were set by Olga.<\/p>\n
