Theodore James Courant
American mathematician
Theodore James "Ted" Courant is an American mathematician who has conducted research in the fields of differential geometry and classical mechanics. In particular, he made seminal contributions to the study of Dirac manifolds,[1][2] which generalize both symplectic manifolds and Poisson manifolds, and are related to the Dirac theory of constraints in physics. Some mathematical objects in this field have since been named after him, including the Courant bracket and Courant algebroid.
