Courant Algebroids. A Short History
arXiv:1212.0559 · doi:10.3842/SIGMA.2013.014
Abstract
The search for a geometric interpretation of the constrained brackets of Dirac led to the definition of the Courant bracket. The search for the right notion of a "double" for Lie bialgebroids led to the definition of Courant algebroids. We recount the emergence of these concepts.
