摘要 鉴于l_1范数锥投影算子性质在研究l_1范数锥规划、l_1范数锥互补问题、l_1范数锥均衡约束优化问题等方向理论、算法及应用时的重要性,本文给出了l_1范数锥投影算子的计算公式,以期为l_1范数锥相关问题的进一步研究提供一定的理论基础. The properties of the projection operator play important roles in the study on theory, methods and applications of l1-norm cone programming,l1-norm cone complementarity problems and optimization problems with l1-norm cone equilibrium constraints. This paper derives the formulae of the projection operator onto the l1-norm cone so that it can serve as theoretical basis to further study more relevant problems.
