摘要：

We study a class of matrix function algebras, here denoted T+(C-n). We introduce a notion of point derivations, and classify the point derivations for certain finite dimensional representations of T+ (C-n). We use point derivations and information about n x n matrices to show that every T+(C-n)-valued derivation on is inner. (c) 2006 Elsevier Inc. All rights reserved.
