Matrix Identities and Determinant Identities for Composite Functions Xinghua Wang 1, Aimin Xu 2 1 Department of Mathematics, Zhejiang University, Hangzhou 310027, China2 Institute of Mathematics, Zhejiang Wanli University, Ningbo 315100, China Received 2009-3-9 Accepted 2010-2-4 Available online 2010-9-20 doi:10.4208/jcm.1004-m3067 Abstract We present some matrix and determinant identities for the divided differences of the composite functions, which generalize the divided difference form of Fa\`{a} di Bruno's formula. Some recent published identities can be regarded as special cases of our results. Key words: Bell polynomial, Composite function, Determinant identity, Divided difference, Matrix identity.
