摘要：

Electronic properties of Ce-based heavy-fermion compounds are discussed by using the relativistic band-calculation method. To seek for a route from the band calculation to a many-body Hamiltonian, which is necessary to discuss the magnetic and superconducting properties, a minimal tight-binding model is proposed for f-electron systems.
