摘要:我们考虑配备所有对称正半定矩阵锥体 n+ 的实对称 n×n 矩阵的空间 n 中的半定单调线性互补问题(SDLCP)。通过用 (XY+YX)/2=rM 替换标准条件 XY=rI, r>0(定义通常的中心路径),可以定义加权(使用任何 M∈n++ 作为权重)不可行的内点路径。在一些温和的假设下(最严格的是(SDLCP)存在一些严格互补的解),这些路径的极限为r↓0,并且它们在分析上取决于所有路径参数(例如r和M),即使在极限点r=0处也是如此。
Abstract.We consider semidefinite monotone linear complementarity problems (SDLCP) in the space n of real symmetric n×n-matrices equipped with the cone n+ of all symmetric positive semidefinite matrices. One may define weighted (using any M∈n++ as weight) infeasible interior point paths by replacing the standard condition XY=rI, r>0, (that defines the usual central path) by (XY+YX)/2=rM. Under some mild assumptions (the most stringent is the existence of some strictly complementary solution of (SDLCP)), these paths have a limit as r↓0, and they depend analytically on all path parameters (such as r and M), even at the limit point r=0.
