Interesting is the failure of things like the Hahn-Banach theorem. Indeed the dual space of L_p(0,1) for p<0 contains only the zero vector!
Even more interesting is the same thing for the case 0 < p < 1.
Um, yes! Sorry about that.
(Actually p<0 also makes sense in some contexts, but that is, of course, not what I meant!)
