In this paper, we investigate some properties of the domains c0(Cn), c(Cn), and ℓp(Cn) with 0 < p < 1 of the Cesàro matrix of order n in the classical spaces c0, c, and ℓp of null, convergent, and absolutely p‐summable sequences, respectively, and compute the α‐, β‐, and γ‐duals of these spaces. We characterize the classes of infinite matrices from the space ℓp(Cn) to the spaces ℓ∞, c, and c0 and from a normed sequence spaces to the sequence spaces c0(Cn), c(Cn), and ℓp(Cn). Moreover, we compute the lower bound of operators from ℓp into ℓp(Cn), from ℓp(Cn) into ℓp and from ℓp(Cn) into itself.

在Cesàro的空间上,绝对p可加,零和收敛序列
在本文中,我们研究了结构域的一些性质Ç 0(Ç Ñ),Ç(Ç Ñ),和ℓ p(ç Ñ)与0 < p <1的顺序的Cesàro平均矩阵的Ñ在古典空间Ç 0,ç,和ℓ p空,会聚,和绝对的p -summable序列,分别与计算α - ,β - ,和γ这些空间的对偶。我们从空间表征无限矩阵的类ℓ p(Ç Ñ)到空间ℓ ∞,Ç,和Ç 0和从赋范序列空间的序列空间Ç 0(Ç Ñ),Ç(Ç Ñ),和ℓ p(ç ñ)。此外,我们计算下界从运营商的ℓ p到ℓ p(Ç Ñ),从ℓ p(ç Ñ)成ℓ p和从ℓ p(ç Ñ)到其自身。
