摘要：

We study a strong-coupling expansion of a 4 quantum field theory with an O(N) internal symmetry. For large values of N we observe that there is a critical point in 2<D<4 dimensions and recover the known results for the two-point and the four-point Green's functions near the critical point, and for the critical exponent. © 1979 The American Physical Society.
