摘要
本文引进了一种广义严格拟凸函数的定义 ,给出了它的一个刻画 。
In this paper, a definition of nonconvex functions, called generalized strictly quasiconvex functions is introduced, and it is proved that a real function has the property that every local minimum is global, if and only if it is the generalized strictly quasiconvex function, and by the level sets, a characterization of the generalized strictly quasiconvex funcion is given.
