Let (E, τ) be a topological vector space with a basis {e i}, F={f i} be the coordinate functional which is determined by {e i}, λ be a scalar sequence space with the weak gliding hump property. In this paper, we show that if the series ∑ix i in (E, τ) is λ multiplier convergent with respect to σ(E,F), then ∑ix i is also λ multiplier convergent with respect to τ. By using this result, we improve the famous Stiles Orlicz Pettis theorem, and enlarge an invariant property range in locally convex spaces with a basis.
