Then, two necessary conditions for second-orderoptimality for the weak minimal in the vector optimization of set-valued maps are obtained.
然后,获得了集值向量优化问题弱极小元的两个二阶最优性必要条件。
This paper further puts forward the minimal weak ideal of rings, and discusses some of its properties, and comes out with some results.
