Abstract
The notion of vector valued sequence space is a generalized form of spaces of scalar valued sequences, and its terms consist of sequences from a vector space. In this work, we shall study some conditions that characterize the linear space structures and containment relations of the space of sequences whose terms from a product normed space.
The aim of this paper is to deal with a vector valued sequence space 1∞ (A x B, || . || , 
,ū ) with its terms from a product normed space A x B. We shall also investigate the linear space structure of 1∞(A x B, || . ||, ,ū ) with respect to co-ordinatewise vector operations, the primary interest is to explore the conditions in terms of and so that a class 1∞ ( A x B, || . ||, ,ū ) is contained in or equal to another class of the same kind.
Keywords: Sequence space, generalized sequence space, product normed space.
