higher order cotangent bundle; natural affinor
All natural affinors on the $r$-th order cotangent bundle $T^{r*}M$ are determined. Basic affinors of this type are the identity affinor id of $TT^{r*}M$ and the $s$-th power affinors $Q^s_M : TT^{r*}M \rightarrow VT^{r*}M$ with $s=1, \dots , r$ defined by the $s$-th power transformations $A^{r,r}_s$ of $T^{r*}M$. An arbitrary natural affinor is a linear combination of the basic ones.
