The essential norm of multiplication operators acting on Orlicz sequence spaces

Abstract We calculate the measure of non-compactness or the essential norm of the multiplication operator M u acting on Orlicz sequence spaces l ϕ . As a consequence of our result, we obtain a known criteria for the compactness of multiplication operator acting on l ϕ .
