We prove a converse of Yano's extrapolation theorem for translation invariant operators.
We introduce and investigate a new sectional property for topological sequence spaces, which we call the KB property. It turns out that multipliers into l ∞ and multiplication by l 1 play a very similar role for KB as multipliers into bs and multiplication by bv 0 do for the well-known sectional pro
