关于拟导数的性质

ON THE PROPERTIES OF PSEUDO-DERIVATIVES

本文对形如Ｍｆ±Ｎｇ（Ｍ≥０Ｎ≥０）形式的函数的拟导数（Ｍｆ±Ｎｇ）′ｘ的存在性及其与Ｍｆ′ｘ±Ｎｇ′ｘ的关系进行了研究。

This paper investigates the differentiability of such function as Mf±Ng(g(M≥0,N≥0)and the relations between the pseudo-derivative of Mf±Ngand Mfx′±Ngx′.The results obtained in this paper improve and extend some of the existing results.
