Abstract:

We introduce the notion of mIT-structures determined by operators mInt and mCl on an m-space . By using mIT-structures, we introduce and investigate the new classes of multifunctions called upper/lower mIT-continuous. As special cases of upper/lower mIT-continuity, we obtain upper/lower -M continuity [34] and upper/lower -M-precontinuity [35].

Keywords:

m-structure, m-continuous, mIT-structure, mIT-continuous, multifunction.
