Multiplication Operator on Köthe Spaces: Measure of Non-compactness and Closed Range

"We calculate the measure of non-compactness of the multiplication operator Mu acting on non-atomic Köthe spaces. We show that all bounded below multiplication operators acting on Köthe spaces are surjective and therefore bijective and we give some new characterizations about closedness of the...
