摘要
本文引入集值映射的锥下半连续概念,给出并证明了集值映射锥上半连续、锥下半连续、锥连续的几个充分必要条件,锥上半连续集值映射的弱下水平闭性质和锥下半连续集值映射的强上水平闭性质.
In this paper we introduced cone-lower-semicontinuity of set-valued map, then gave and proved several equivalence discriptions of cone-upper-semicontinuity, cone-lower-semicontinuity, and cone-continuity of set-valued map, and two properties for cone-upper-semicontinuity, cone-lower-semicon- tinuity of set-valued map.
