Description
I will talk about some recent progress on non-perturbative SL(2,Z) duality in nonrelativistic string theory, which is a self-contained string theory that has a string spectrum with a Galilean invariant dispersion relation. I will show that the SL(2,Z) duality in this string theory exhibits intriguing new structure. This study provides a precursor towards realizing novel U-duality relations between nonrelativistic and discrete light-cone quantization (DLCQ) string/M-theory, where DLCQ appears in non-perturbative approaches to quantum field theory and string/M-theory, such as in matrix model.
