Complementarity and Related Problems

Lianghai Xiao

摘要:

在这篇论文中,我们给出了与互补性问题相关的结果。研究了扩张二阶锥上的线性互补性问题。将扩张二阶锥上的线性互补性问题转化为非负正交点上的混合互补性问题。本文给出了求解该问题的算法,并通过一个数值例子进行了验证。根据这一结果,我们探讨这个线性互补性问题的随机版本。最后,我们将扩展二阶锥上的互补性问题应用于投资组合优化问题。在这个应用程序中,我们利用我们的理论结果找到一个新的投资组合优化模型的解析解。我们还研究了球自对偶凸集上二次函数的球拟凸性。我们从探索球面正正交的特征和条件开始这项研究。给出了二次函数球拟凸的几个条件。然后,我们推广到球自对偶凸集上的球拟凸性条件。特别是,我们突出的情况下,球形二阶锥。

英文摘要:

In this thesis, we present results related to complementarity problems. We study the linear complementarity problems on extended second order cones. We convert a linear complementarity problem on an extended second order cone into a mixed complementarity problem on the non-negative orthant. We present algorithms for this problem, and exemplify it by a numerical example. Following this result, we explore the stochastic version of this linear complementarity problem. Finally, we apply complementarity problems on extended second order cones in a portfolio optimisation problem. In this application, we exploit our theoretical results to find an analytical solution to a new portfolio optimisation model. We also study the spherical quasi-convexity of quadratic functions on spherically self-dual convex sets. We start this study by exploring the characterisations and conditions for the spherical positive orthant. We present several conditions characterising the spherical quasi-convexity of quadratic functions. Then we generalise the conditions to the spherical quasi-convexity on spherically self-dual convex sets. In particular, we highlight the case of spherical second order cones.
