Ivo M. Babuška (born March 22, 1926 in Prague) is a Czech-American mathematician, noted for his studies of the finite element method and the proof of the Babuška-Lax-Milgram theorem in partial differential equations. One of the celebrated result in the finite elements is the so-called Babuska-Brezzi (BB) condition, which provides sufficient conditions for a stable mixed formulation. The BB condition has guided mathematicians and engineers to develop state-of-the-art formulations for many technologically important problems like Darcy flow, Stokes flow, incompressible Navier-Stokes, nearly incompressible elasticity. He is also well known for his work on adaptive methods and the p- and hp-versions of the finite element method. He also developed the mathematical framework for the partition of unity methods.
