While normally doped infinite layer nickelate is regarded as a d-wave superconductor like cuprates, we have analyzed entire doped region that contains heavier doped region at whch the synthesis has not been achieved. The procedure is two steps: first-principles calculation and many body calculation based on the results of that. Through this calculations, the possibilty of s-wave superconductor not triggered by phonon mechaism especially at heavior doped region. In the presentation, we will also discuss its similarity with the bilayer nickelate superconductor.
