Generalized difference entire sequence spaces

in this paper we introduce difference entire sequence spaces and difference analytic sequence spaces defined by a sequence of modulus function f = (/？) and study some topological properties and some inclusion relations between these spaces. we also make an effort to study some properties and inclusion relation between the spaces tf(á？ , u, p, q, ||., ···, .||) and af(a^ , u, p, q, ||., ·· ·, .\\).
