Abstract:
If $E$ belongs to a certain category of Banach spaces (the ${B^\infty }$-smooth spaces) which include Hilbert spaces and if $F$ is any normed space, it is proved that any local linear automorphism of ${C^\infty }(E,F)$ is a differential operator. This generalizes a result of J. Peetre when $E = {R^n}$ and $F = R$.References
