In this paper, we first prove global well-posedness for the defocusing cubic nonlinear Schrödinger equation (NLS) on 4-dimensional tori - either rational or irrational - and with initial data in H1. Furthermore, we prove that if a maximal-lifespan solution of the focusing cubic NLS u: I×\mathbbT4→ ℂ satisfies supt∈ I‖u(t)‖_H1(\mathbbT4)
