In the present paper, we introduce the sequence space lλp of non-absolute type and prove that the spaces lλp and lp are linearly isomorphic for 0 < p ≤ ∞. Further, we show that lλp is a p-normed space and a BK-space in the cases of 0 < p < 1 and 1 ≤ p ≤ ∞, respectively. Furthermore, we derive some inclusion relations concerning the space lλp. Finally, we construct the basis for the space lλp, where 1 ≤ p < ∞.
