摘要：

We describe a new approach to the ground state antiferromagnetic phase of the infinite-dimensional Hubbard model. The theory recovers correctly both the strong coupling Heisenberg limit at 1/2 filling and the t-J limit in the one-hole sector, appears applicable over a wide U range, and is readily extended to finite dimensions.
