Abstract
The main purpose of this manuscript is to introduce Banach spaces \(c_0^\Phi \) and \(c^\Phi \) as the matrix domain of a regular matrix \(\Phi \) derived by the Euler totient function. These spaces consist of \(\varphi \)-convergent to zero and \(\varphi \)-convergent sequences, respectively. After determining \(\alpha \)-, \(\beta \)- and \(\gamma \)-duals of these spaces, some matrix classes are characterized. Finally, using the Hausdorff measure of noncompactness, the characterization of some classes of compact operators on the space \(c_0^\Phi \) is given.
