| Apr 23 at 20:15 | comment | added | Denis T | In some sense "naive smooth coalgebras" of nonzero dimension cannot exist. What I mean is that induced comultiplication on the (algebraic, not topological) dual vector space to a smooth ring never lands inside non-completed tensor square; it's easy to see that by multiplying together bump functions on small disjoint disks. With a bit more care one can say the same thing even for l.c.s. dual. | |
