摘要：

The ground-state energy of the antiferromagnetic Heisenberg model on the kagome lattice (S = 1) is calculated with use of the perturbational expansion around the ''trimer state''. The present result is compared with that of the spin-wave calculation. The first excited energy is also evaluated. Some solvable models are introduced.
