Summary: We define the sequence spaces
where for instance
, give some topological properties, inclusion relations of these spaces and compute their continuous and Köthe-Toeplitz duals. Furthermore, we characterize some matrix classes related to these sequence spaces. This study generalizes some results of the first author [Turk. J. Math. 17, No. 1, 18-24 (1993; Zbl 0826.40001
)] and H. Kizmaz
[Can. Math. Bull. 24, No. 2, 169-176 (1981; Zbl 0454.46010
)] in special cases.
