New sequence spaces introduced via Bell matrix, determining Köthe–Toeplitz duals in this context.
In this work, new sequence spaces are introduced via the recently formulated Bell matrix, their Köthe–Toeplitz duals are determined, and a corresponding Schauder basis is established. In addition, various operator classes acting on these spaces are examined.
