New types of multifunctions in ideal topological spaces via $e$-$\I$-Open sets and $\delta\beta$-$\I$-Open sets
The purpose of the present paper is to introduce and investigate two new classes of continuous multifunctions called upper/lower $e$-$\I$-continuous multifunctions and upper/lower $\delta\beta_I$-continuous multifunctions by using the concepts of $e$-$\I$-open sets and $\delta\beta_I$-open sets. The...
