Abstract
The author shows that a very large class of two-dimensional Z(N) spin models with multi-spin interactions is self-dual. By using Griffiths-like inequalities on correlation functions he expects that all these theories, for N sufficiently large, will show an intermediate disordered massless phase (infinite correlation length) between massive high- and low-temperature phases.Keywords
