Jun 17, 2015 at 23:46 comment added David Roberts Thanks, TaQ, I've added your example to the nLab page ncatlab.org/nlab/show/Michal-Bastiani+smooth+maps, citing this answer. I may ask another question in future about MB-smooth bijections with only convenient smooth inverse. But that's another question.
Jun 17, 2015 at 20:03 comment added TaQ To clarify a bit: " $x_i=0$ for sufficiently small $i$ " means more precisely that " there is $i_0\in\mathbb Z$ such that $x_i=0$ for all $i\in\mathbb Z$ satisfying $i\le i_0$ ". This $i_0$ of course depends on $x$ . The discontinuous (and hence not MB−smooth) convenient diffeomorphism is the map $f:E\to E$ .
