Overview

About Olga Ladyzhenskaya

Olga Ladyzhenskaya was a mathematician whose work advanced the theory of partial differential equations and mathematical fluid dynamics. She established important existence, uniqueness, and regularity results for equations describing viscous incompressible flow, including the Navier-Stokes equations in two dimensions. Her methods influenced modern analysis and the mathematical study of continuum mechanics. She became one of the leading figures of twentieth-century Russian mathematics.
