Operator ideal of Cesaro type sequence spaces involving lacunary sequence
Summary: The aim of this paper is to give the sufficient conditions on the sequence space \(\mathrm{Cs} (\theta, p)\) defined in [\textit{K.-P. Lim}, Tamkang J. Math. 8, 213--220 (1977; Zbl 0405.46005)] such that the class of all bounded linear operators between any arbitrary Banach spaces with \(n\)th approximation numbers of the bounded linear operators in \(\mathrm{Cs} (\theta, p)\) form an operator ideal.
