The finite and large-<i>N</i> behaviors of independent-value matrix models
We investigate the finite and large $N$ behaviors of independent-value O(N)-invariant matrix models. These are models defined with matrix-type fields and with no gradient term in their action. They are generically nonrenormalizable but can be handled by nonperturbative techniques. We find that the functional of any O(N) matrix trace invariant …
