摘要
定义了一类广义正线性集，它是增广对偶锥的推广．利用广义正线性集中元素定义了一类单调次线性函数，并研究了这类函数的相关性质．
In this thesis, we define a kind of generalized positive linear sets, which is a generalization of the dual cones. By using elements of generalized positive linear sets, we give the notion of monotonically increasing sublinear function and study the properties of these functions.
