Abstract
We describe the structure of models with effective many-fermion interaction and a finite cutoff in the symmetry-breaking regime. The large-Nc tadpole mechanism for the DSB and the fine-tuning condition in providing the scale invariance are used to classify the set of quasilocal vertices relevant for the dynamic mass formation. It is found that in such effective models the vertices with four, six and eight fermions only should be retained in four-dimensional space.
