Matrix models of 2d gravity

Web8 mei 2024 · In this way, you get a matrix model that has a genus expansion over 2D smooth surfaces – a 2D gravity theory. That’s the double scaling limit. There are many ways of doing this, corresponding to many different kinds of 2D gravity theory (for example, coupled to different kinds of 2D fields), so SSS had to piece together what kind of matrix ...
