-The special cases of the [[o2_model]] and [[o3_model]] are particularly well-studied. The [[Ising model]] should probably be viewed as a special case as well, with $N=1$.+The special cases of the [[o2_model]] and [[o3_model]] are particularly well-studied. Higher values of $N$ do come up occasionally, see for instance the [[o4_model]]. The [[Ising|Ising model]] is the case $N=1$, and the case $N=0$ is covered by  [[self_avoiding_walk|self-avoiding walks]].

 +This also goes by the name of the "n-vector model", or "non-linear $\sigma$ model$.
