【Abstract】 The main purpose of this paper is to study expansive directions for norm bodies in the CM-problem with convex and complementary convex constraints. Some expansive conditions are proposed. The study is based on an aspect of geometry. Results in this paper would be helpful to study of algorithms for solving the CM-problem.更多还原
