Feng, Chunqiang; Xu, Yusheng; Liu, Yong; Yuan, Wenfa The derivation of bounded functions. (English) Zbl 1131.30363 Basic Sci. J. Text. Univ. 20, No. 2, 143-145, 148 (2007). Summary: In this paper, we mainly discuss the problem of estimating the derivation of bounded functions. A general estimation of the \(n\)-th derivation of regular function is presented by using the maximum modulus principle and the properties of the bounded functions. Hence, the results of bounded regular functions have been given from special to general.
