Recently, superconductivity has been observed in infinite-layer, bilayer, and trilayer nickelates. In particular T_c of about 80K was observed in the bilayer La₃Ni₂O₇ under pressure. We have considered the possibility of superconductivity in this material before its discovery, and have also predicted the possibility of superconductivity in the trilayer La₄Ni₃O₁₀. In this symposium talk, these theoretical studies will be explained in detail.
