摘要:
The splitting problem is studied for short exact sequences consisting of countable projective limits of DFN-spaces (*) 0 --> F --> X --> G --> 0, where F or G are isomorphic to the space of distributions D'. It is proved that every sequence (*) splits for F similar or equal to D' iff G is a subspace of D' and that, for ultrabornological F, every sequence (*) splits for G similar or equal to D' iff F is a quotient of D'.
