Abstract: | Given a space (U) of functions f:U which are continuous, we construct another space *(U) and a map e:U *(U) linearizing all functions f (U) (i.e. there are Lf *(U) such that Lf^e=f). Such linearizations are stronger than mere preduals for (U), for example for (U)= 1, linearizations correspond to preduals of 1 which are isomorphic to c0. We also address the vector-valued case. A number of such linearizing constructions are to be found in the literarture, mostly for certain spaces of holomorphic functions. The procedure presented here generalizes all these special cases.Mathematics Subject Classification (2000):46E10, 46G20 |
