Lingchen Kong, Levent Tunçel, Naihua Xiu

摘要:

考虑齐次锥互补性问题(HCCP)解的存在唯一性.利用齐次锥的$T$ -代数特征,将标准非线性互补性问题中的非线性函数的$P, P_0, R_0$性质推广到HCCP的情形.证明了如果一个连续函数具有序- $P_0$和$R_0$,或者具有$P_0$和$R_0$性质,那么所有相关的HCCP都有解.特别地,如果连续函数具有跟踪- $P$属性,则关联的HCCP具有唯一解(如果有的话);如果它具有均匀跟踪- $P$属性,则关联的HCCP具有(解的)全局唯一性属性(GUS)。给出了非线性变换具有GUS性质的一个必要条件。此外,我们建立了一个全局误差界的HCCP与均匀迹$P$性质。最后,我们研究了$T$ -代数上带有松弛变换的HCCP和齐次锥线性互补性问题的自同构不变性质。

英文摘要:

We consider existence and uniqueness properties of a solution to homogeneous cone complementarity problem (HCCP). Employing the $T$-algebraic characterization of homogeneous cones, we generalize the $P, P_0, R_0$ properties for a nonlinear function associated with the standard nonlinear complementarity problem to the setting of HCCP. We prove that if a continuous function has either the order-$P_0$ and $R_0$, or the $P_0$ and $R_0$ properties then all the associated HCCPs have solutions. In particular, if a continuous function has the trace-$P$ property then the associated HCCP has a unique solution (if any); if it has the uniform-trace-$P$ property then the associated HCCP has the global uniqueness (of the solution) property (GUS). We present a necessary condition for a nonlinear transformation to have the GUS property. Moreover, we establish a global error bound for the HCCP with the uniform-trace-$P$ property. Finally, we study the HCCP with the relaxation transformation on a $T$-algebra and automorphism invariant properties for homogeneous cone linear complementarity problem.
