Abstract
We revisit a result from “Pointwise convergence of the Schr ̈odinger
flow, E. Compaan, R. Luc`a, G. Staffilani, International Mathematics Research
Notices, 2021 (1), 596-647” regarding the pointwise convergence of solutions
to the periodic cubic nonlinear Schr ̈odinger equation in dimension d = 2.
