(h,φ)-伴随切锥及其性质

(h,φ)-Contingent Cone and its Properties

讨论了(h,φ)-伴随切锥的性质。通过具体例子说明它是伴随切锥的推广,给出了复合函数取下极限的性质,籍此和Ben-Tal广义代数运算的性质给出了(h,φ)-伴随切锥的两种等价刻画,为计算伴随切锥提供了一种方法。

Properties of（h,φ）-contingent cone were investigated.An example was given to show that it was a generalization of contingent cone.A property for low limit of composite function was presented,by which and Ben-Tal algebraic operation,two kinds of equivalent（h,φ）-characterizations were established.Hence a method for calculating contingent cone was provided.
