Some complemented function spaces in C(X)

Daniel Eliot Wulbert

Vol. 24 (1968), No. 3, 589–602

et X and Z be compact Hausdorff spaces, and let P be a linear subspace of C(X) which is isometrically isomorphic to C(Z). In this paper conditions, some necessary and some sufficient, are presented which insure that P is complemented in C(X). For example if X is metrizable, P contains a strictly positive function, and the decomposition induced on X by P is lower semi-continuous then P is complemented in C(X).
