In this note, we consider the derivative nonlinear Schrodinger equation on the circle. In particular, by adapting Wu's recent argument to the periodic setting, we prove its global well-posedness in H-1 (T), provided that the mass is less than 4 pi. Moreover, this mass threshold is independent of spatial periods.
