TY - JOUR TI - A weak form of some types of continuous multifunctions AU - Ekici Erdal AU - Park Jin Han JN - Filomat PY - 2006 VL - 20 IS - 2 SP - 13 EP - 32 PT- Article AB- The aim of this paper is to introduce and study upper and lower almost -continuous multifunctions as a generalization of some types of continuous multifunctions including almost continuity, almost -continuity, almost precontinuity, almost quasi-continuity and - continuity. Furthermore, basic characterizations, preservation theorems and several properties concerning upper and lower almost -continuous multifunctions are investigated. The relationships between almost - continuous multifunctions and the other types of continuity are also discussed.
