Abstract
It is widely believed that the critical properties of several planar lattice systems like the Eight Vertex or the AshkinTeller models are well described by an effective continuum fermionic theory obtained as a formal scaling limit On the basis of this assumption several extended scaling relations among their indices were conjectured We prove the validity of some of them among which the ones predicted by Kadanoff Phys Rev Lett 39903–905 1977 and by Luther and Peschel Phys Rev B 123908–3917 1975
