Hi,
(Question updated)
My question is about the space of distributions of finite order mathcalD′F (say on mathbbRn). What do we know about it ?
From in the information I gathered, it seems that the natural topology on mathcalD′F is
the inductive limit topology of the spaces (mathcalD′m) of distributions of order m, or equivalently, the dual topology of mathcalDF [ this space being mathcalD as a set, but with the coarser topology of the projective limit (mathcalDm) (Cm functions with compact support, this is an inductive limit of Fréchet spaces with obvious semi-norms).
Note that mathcalDF is strictly coarser than mathcalD (and strictly finer than the mathcalS), and that mathcalD′F is strictly finer than mathcalD′ (and strictly coarser than mathcalS′).
So, the question is: what do we now about this topology on mathcalDF, and its strong dual mathcalD′F ?
It is clearly not Frechet, but is it complete ? Montel? Barrelled ? Nuclear ? Reflexive ?
More generally, do we have most of the nice properties of mathcalD′ for mathcalD′F
?
Thanks
