We investigate the Fermi liquid in the infinite-U degenerate Anderson lattice using expansion from the limit of large spin-orbital degeneracy N. By collecting all diagrams up to O(N-2), we show that the imaginary part of the self-energy of the conduction electrons is given by a form proportional to (omega - mu)(2) + pi(2)T(2). We also show that the Luttlinger sum rule holds up to O(N-1). This implies that the literal 1/N-expansion procedure correctly describes the Fermi liquid in the U-infinite Anderson lattice.
