论文摘要
众所周知,适用于全体形态函数$ f $的Cauchy的论点原则要求$ f $在集成的曲线上没有零。在简短的说明中,我们对这样的原则进行了概括,该原则涵盖了$ f $在曲线上具有零的情况以及应用程序时的情况。
It is known that the Cauchy's argument principle, applied to an holomorphic function $f$, requires that $f$ has no zeros on the curve of integration. In this short note, we give a generalization of such a principle which covers the case when $f$ has zeros on the curve, as well as an application.
