英文摘要:
In this paper, as a first step in examining the properties of a feasible portfolio subset that is characterized by budget and risk constraints, we assess the maximum and minimum of the investment concentration using replica analysis. To do this, we apply an analytical approach of statistical mechanics. We note that the optimization problem considered in this paper is the dual problem of the portfolio optimization problem discussed in the literature, and we verify that these optimal solutions are also dual. We also present numerical experiments, in which we use the method of steepest descent that is based on Lagrange\'s method of undetermined multipliers, and we compare the numerical results to those obtained by replica analysis in order to assess the effectiveness of our proposed approach.

中文摘要:
在本文中,作为检验以预算和风险约束为特征的可行投资组合子集性质的第一步,我们使用复制分析来评估投资集中度的最大值和最小值。为此,我们应用统计力学的分析方法。我们注意到,本文考虑的优化问题是文献中讨论的投资组合优化问题的对偶问题,并且我们验证了这些最优解也是对偶的。我们还进行了数值实验,其中我们使用了基于拉格朗日待定乘子方法的最速下降法,并将数值结果与副本分析得到的结果进行了比较,以评估我们提出的方法的有效性。
