摘要：

The recently proposed Kazakov-Migdal model appears to be trivial as an induced gauge theory at large N, at least in the strong coupling regime. It is enough to know only the trivial Wilson loops that are treelike, just a constant part of the induced gauge action, to compute the free energy at large N. This is a consequence of the fact that the model is solvable by a saddle-point method that is known to sum only the tree graphs.
