I.e. a bounded positive functional defined on a subcone of a normed cone extends to a positive funnctional on the whole cone of the same norm. (That the norm is monotone is important!!) A proof is very similar to the standard Hahn-Banach for vector spaces. I'll, hopefully post it, when I have more time. | |
