Unification of Decoupling Limits in String and M-theory

Chris D. A. Blair, Johannes Lahnsteiner, Niels A. Obers, Ziqi Yan

Abstract

We study and extend the duality web unifying different decoupling limits of type II superstring theories and M-theory. We systematically build connections to different corners, such as Matrix theories, nonrelativistic string and M-theory, tensionless (and ambitwistor) string theory, Carrollian string theory, and Spin Matrix limits of AdS/CFT. We discuss target space, worldsheet, and worldvolume aspects of these limits in arbitrary curved backgrounds.
