Oct 28, 2020 at 9:35 comment added Motaka Yes, nonlinaer here means "not necessarily linear" and not "it cannot be linear".

Oct 28, 2020 at 6:49 comment added Pietro Majer "Nonlinear" usually means "not necessarily linear", like in "nonlinear Fredholm operator", etc.
Oct 28, 2020 at 3:18 comment added LSpice Ah. I assumed "nonlinear" meant "it cannot be linear", but "not necessarily linear" seems like a more reasonable reading.
Oct 27, 2020 at 23:40 comment added Pietro Majer The OP asked for a nonlinear map, and linear maps are in particular nonlinear maps, no?
Oct 27, 2020 at 21:52 comment added LSpice What does "it's linear, therefore nonlinear" mean?
Oct 27, 2020 at 21:39 comment added Pietro Majer Oh, and I forgot to mention that here $T$ is the shift $u\mapsto u(\cdot-1)$, of course (it's linear, therefore nonlinear. One can make it uniformly bounded by truncation, if needed)
