In 2020 Ìlkhan et al. [10] defined Jordan's totient matrix operator. In this paper, the Jordan totient matrix operator A r and I − converence are used to define two new sequence spaces, C I 0(Φ,Ψ,Υ) (A r) and C I (Φ,Ψ,Υ) (A r), as the domain of the Jordan totient matrix operator A r with respect to the neutrosophic norm. Some results about these sequence spaces are also studied.
