摘要
研究了集值映射的上半拟连续性和下半拟连续性及这两种拟连续性与Blum berg集的关系。
There are various possibilities to introduce the notion of quasi-continuity for multifunctions. The aim of this paper is to present two definitions of quasi-continuity of multifunctions and to prove various results for quasi-continuous multifunctions.
