Please find below a summary by the authors of the developments made in this article:
‘Newton–Cartan gravity is a geometric formulation of Newtonian gravity, based on the nonrelativistic limit of general relativity. In our paper we confront this traditional view of Newton–Cartan gravity with a different approach that starts from the Bargmann algebra, a centrally extended version of the Galilei algebra. This approach emphasizes the analogy with the formulation of general relativity as a gauge theory of the Poincaré algebra. The algebraic method suggests a number of generalizations, for instance to conformal algebras, and to the Newton–Hooke algebra, which would lead to classical gravity induced by nonrelativistic strings.’
