本文对拟可微函数定义了凸化核的概念,并对其具体结构做了进一步的研究,给出了一般拟可微函数为次可微的一个充分条件.
In this paper, the convexificator kernels of quasidifferentiable functions are introduced. The structure of the convexificator kernels is explored, and a sufficient condition of a quasidifferentiable function being subdifferentiable is derived.
