Abstract
It is proved that in forms a holo-morphic family of type (A), where is a closed and convex subset of . In particular, the -accretivity of in is established as an application of the perturbation theorem for linear -accretive operators. The key lies in two inequalities derived by positive semi-definiteness of Gram matrix.
