Description
This is Part II that follows J. Lahnsteiner’s talk. I will extend the duality web of decoupling limits in string theory by a worldsheet approach. I will start with developing the string sigma model associated with Matrix theory. T-dualizing this sigma model leads to a web connecting different corners in type II superstring theories. This duality web unifies Matrix theories (BFSS, IKKT, etc.), tensionless/ambitwistor string theory, spin Matrix theories, Carrollian strings, etc. I will also give an outlook of potential implications of this duality web for the AdS/CFT correspondence and flat space holography.
