多值(S_+)型映象的度理论

On the Degree Theory for Multivalued (S +) Type Mappings

本文的目的是推广张石生和陈玉清（多值（Ｓ）型映象度理论以及不动点定理）的结果·假设Ｌ是闭稠定线性极大单调映象，Ｓ是关于Ｄ（Ｌ）的（Ｓ＋）型多值映象，我们建立具有形式Ｆ＝Ｌ＋Ｓ的多值映象的拓扑度·

This paper is to generalize the results of Zhang and Chen . We construct a topological degree for a class of mappings of the form F=L+S where L is closed densely defined maximal monotone operator and S is a nonlinear multivalued map of class (S +) with respect to the domain of L.
