Domain of Jordan Totient Type Matrix Operator in the Spaces of Convergent and Null Sequences

Abstract

Motivated by $\Phi$-summability, novel matrix operators are produced by the aid of fascinating arithmetical functions. One of them is the Riesz-Jordan totient matrix operator, introduced very recently. The primary purpose of this study is to use this matrix to obtain new spaces as the matrix domain of it in some classical sequence spaces. After presenting basic topological properties and identifying dual spaces, the characterization of certain matrix transformations is studied, defined on the resulting spaces. In the final section, the compactness of the operators on the domain of Jordan totient type matrices in the space of null sequences is researched.
