Compact operators on the spaces and

In [C. Aydin, F. Başar, Some new difference sequence spaces, Appl. Math. Comput. 157 (2004) 677–693] Aydin and Başar introduced the new difference sequence spaces and and characterized the classes and . Here we characterize the subclasses K(X,Y) of compact operators where X is and Y is one of the spaces c0,c,l∞,l1,bv by applying the Hausdorff measure of noncompactness.
