Oswald Veblen - Accomplishments

Accomplishments

During his career, Veblen made important contributions in topology and in projective and differential geometries, including results important in modern physics. He introduced the Veblen axioms for projective geometry and proved the Veblen–Young theorem. He introduced the Veblen functions of ordinals and used an extension of them to define the small and large Veblen ordinals. He was involved in overseeing the World War II work that produced the pioneering ENIAC electronic digital computer. He also published a paper in 1912 on the four-color conjecture.
