    I’d like to understand the relation to jet spaces better. It seems that, strictly speaking, a jet space is not a special case of a jet scheme and vice versa. In SDG terminology if Δ m={εR|ε m+1=0}\Delta_m=\{\epsilon \in R \, | \, \epsilon^{m+1}=0\}, then the jet scheme X m=[Δ m,X]X_m=[\Delta_m,X] right?
