| Abstract | The well known operator ordering ambiguity could motivate the existence of generations. This possibility is explored by exploiting the relationship between ordering and discretization rules. Non Commutative Geometry is not the only area knowing how to get mass terms from nowhere. Lattice theorists learnt time ago a nice trick from Wilson. Consider the forward and backward discrete derivatives, ∂ + , ∂ − as usual ∂ + f (x) = f (x + ǫ) − f (x) ǫ , ∂ − f (x) = f (x) − f (x − ǫ) ǫ Suitable derivatives in the lattice can be implemented as any linear combination of both, |
