A subclass called stable quasiconvex functions in the class of quasiconvex functions is presented.
研究拟凸函数子类稳定拟凸函数的特性,给出稳定拟凸函数及其经线性扰动后与拟凸函数关系的特征刻画,得到严格稳定拟凸函数与严格凸函数的等价条件。
he concepts of quasi-practical stability were introduced in the process of considering discrcte systems of volterra type.
在考虑Volterra到离散系统的过程中,我们引入了拟实用稳定性等概念,并利用差分方程的等价性,获得了线性和非线性Volterra型离散系统拟实用稳定的一些简明判据。
