Abstract
We propose a vertex formulation of the Ising model with inhomogeneous external field on multiconnected networks possessing a superbond struc ture. The related technique based on gauge degrees of freedom enables us to recognize new collective modes of interaction nature, which prov ide an exact solution of the inverse profile problem and an explicit f orm of a local free-energy functional on an extended magnetization-mod e space. Application is made to a square strip.
