摘要:Let Γ 2 denote the spaces of all double entire sequences. Let Λ 2 denote the spaces of all double analytic sequences. This paper is devoted to a study of the general properties of Nörlund space of double entire sequences η ( Γ 2 π ) , Γ 2 and also study some of the properties of η ( Γ 2 π ) and η ( Λ 2 π ).
