In algebraic geometry, the technique of dévissage reduces many questions to the case of curves. In difference and differential algebra, this is not the case, but the obstructions can be closely analysed. In difference algebra, they are difference varieties defined by equations of the form $\si (x) = g x$ $\si (x) = g x$ $\si (x) = g x$ $\si (x) = g x$ $\si (x) = g x$ $\si (x) = g x$ $\si (x) = g x$ $\si (x) = g x$ , determined by an action of an algebraic group and an element g of this group. This is joint work with Zoé Chatzidakis.
